Is there proof a positron exists?
Positrons were first suggested by Paul Dirac in 1928, and they were observed directly in a cloud chamber by Carl D. Anderson in 1932. It should be noted that Caltech graduate student Chung-Yao Chao is credited with detecting the positron in 1930, but he was unable to explain it. As regards Anderson's experiment, it was fairly simple. Highly energetic cosmic rays passing through the cloud chamber interacted with other atoms in a number of pair production events. These high energy gamma rays were actually "creating" matter from electromagnetic energy. A magnetic field set up in the chamber caused the particle pairs, which are an electron and a positron, to be deflected in opposite directions because of their opposite charges. There was only one explanation for the observed results, and this explanation included the existence of a positron, the antiparticle of the electron. Just as Dirac predicted. Positrons have been seen as products in numerous high energy physics experiments. In addition, they are actually used in medical imaging, and we see this in Positron Emission Tomography (PET scan). Without positrons, PET scans wouldn't be possible. Links are provided below for more information.
There is no proof that heaven exists. There are a few scriptural references that provide comfort for believers who wish to hope for an afterlife, but no proof.
No proof of either heave or her that stands up to any scientific or logical examination exists.
no there is not
There is no scientific proof that 'Nessie' exists.
There is no proof he exists.
There is no proof that it is dangerous, or that it actually exists.
To date there is no scientific proof that aliens exist. However scientifically, absence of proof that they exist does not constitute proof that they do not exist.
Proof of it exists only in Plato's writings.
The Rabbit-proof fence exists under various names in Western Australia
Many people claim to have seen the Loch Ness Monster but there is no scientific proof that it exists.
There are no positrons in an atom. A positron is an anti-electron - it's antimatter. It will combine with an electron when it can (pretty much as soon as it can) in mutual annihilation. Both it (the positron) and the electron will have their entire mass converted into energy. In translation, that means a positron (antimatter) will not survive in a "regular" matter universe. It won't exist here with us for very long. But the… Read More
A POSITron has a POSITive charge, hence the name. A positron is an anti-electron; since the electron has a negative charge, the positron has a positive charge.

There is no proof that life exists anywhere but Earth.
Yes, there is a workshop at the North Pole.
There is really no absolute proof that Bigfoot even exists.
No there proof that exists is very bad, he does not worship the devil people who think that are brainwashed.
This is the thing, there is no proof of there being a God see? Humans think that you can believe in something without knowing that it exists.
Of course god exists. READ THE BIBLE AND YOU WILL FIND OUT. Answer: No defensible proof exists for the existence of a deity in any religion except in their own religious writings. Nonbelievers point out that these "proofs" are fallacious arguments lacking objectivity and demonstrability.
The stories say he is a "jolly old elf" which would mean Santa is not a regular person, so you won't find proof that he exists like a regular person. All we really have is circumstantial evidence: presents.
The belief that there can be no proof either that God exists or that God does not exist.
There is no real proof that this underwater city exists
'course or people woudn't think it exists...
there are many texts in books and accounts by famous historians
Since the positron is the antiparticle of the electron, it follows that the electron is the antiparticle of the positron.
Essentially, there has never been any quantifiable proof that bigfoot exists.
There is no definitive proof that ESP exists and therefore no definitive advice as how to develop it.
There is no proof that demons exists in Norway or any other parts of the world.
1.It's aliens not aligns 2.We have no proof, but nothing is impossible
A positron is similar to an electron.
There is no objective proof that God exists, or did exist in the past. However, Christians universally believe that he has always existed and always will.
The document exists in order to furnish proof. It is reasonable to think that at some time you could be asked to show the proof.
Yes, the positron is considered to be a lepton.
Scientists are skeptical about the Loch Ness monster because there is no solid proof that the monster exists. They will do nothing about it until there is some proof.
There is no proof that Zeus exist. I do agree with the first answer that there is no proof that he exists but in Roman times Zeus was Jupiter. (he was not named after the planet, the planet was named after him.)
There is no certain proof that bigfoot exists. However, if so, it can be said the he or she does not like company.
there are no photos. The only evidence is alot of eyewitness reports
Yes. Antiparticles are regularly produced and observed in particle accelerators.
There is no proof that the Egyptian gods exist, just as there is no absolute proof that they do not exist. Because of the historical success of Christianity and Islam, it is simply assumed that, therefore, God exists but the ancient gods of Egypt do not.
No, a positron cannot react with a neutron in any kind of annihilation reaction. An electron and a positron can, and the same with a neutron and an anti-neutron, but it does not occur between a positron and a neutron.
there are river beds which must have Bean carved by water
Only in theoretical science: there has been no physical proof that one exists anywhere.
There is no proof of alien life, if they exists they could have aquatic characteristics.
Descartes uses this statement to prove that he exists: "I think, therefore I am." He uses this as proof because him thinking shows he is capable of having a free will and keeping his own opinions.
No there is no exact proof because all we know is that the value of pi is a circle's circumference divided by its diameter which is an irrational number that has never been finally determined. The existence of pi needs no proof, it exists by definition and has a well defined known value by that definition. However as pi is an irrational number that value cannot be written completely in any standard number base system… Read More
Answer Many have tried to prove God exists. Some of the suggestions have been that God 'must' have created the world, the Bible contains prophecies or even that God exists because the Bible says so. But no one has ever provided undeniable proof that God exists.
The mass of a positron is approximately 9.1093826(16) × 10−31 kg. The positron and the electron are anti-particles of each other, and you can find out more about the positron at the Wikipedia article on that subject. A link to their post can be found below. There is also a link to a related question on the nature of the positron. That's down there, too.
belief, accepting something as truth without the burden of proof or evidence. I don't know China exists, I've never been there and seen it with my own eyes, I have no proof. But I believe the people who have, I accept their experience as truth.
There is technically no such thing as positron decay. It's a misnomer. The nuclear decay process wherein a positron is emitted from a decaying nucleus is called positron emission or beta plus decay. A link is provided below that question and its answer.
A: Agnostics are people who accept that there is no proof that God (or gods) exists, but are not entirely convinced that he does not exist. So they are simply unsure whether there is a God. Since a great many Christians also accept that there is no proof that God exists but still hold faith he does and worship him, to be an agnostic can be an intellectually honest position.
That is called an anti-electron, also known as a positron. That is called an anti-electron, also known as a positron. That is called an anti-electron, also known as a positron. That is called an anti-electron, also known as a positron.
