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.

What is the anti-matter equivalent of an electron?
No. The antiparticle for the proton is called antiproton. The antiparticle for the electron is called antielectron, also known as positron.
What Is geological positron emission?
loss of a positron. 0:+1B
Is there any proof that antimatter exists?
Yes. Antiparticles are regularly produced and observed in particle accelerators.
What is the symbol for a positron?
A positron is the antiparticle of the electron. We write the electron as e- as it is negatively charged. We write e+ or β+ for the positron. The latter symbol uses the Greek letter beta as positron emission is one of the two forms of the radioactive decay known as beta decay. Links can be found below.
The emission of a positron also results in the creation of?
If you are talking about beta+ decay, then the emission of a positron is accompanied with the emission of an electron neutrino.
Is there proof that hell exists?
No proof of either heave or her that stands up to any scientific or logical examination exists.
Is there any scientific proof that dont exists?
no there is not
Why is the yeti dangerous?
There is no proof that it is dangerous, or that it actually exists.
Does Nessie have babies?
There is no scientific proof that 'Nessie' exists.
God is so not real right?
There is no proof he exists.
Is there any logical proof that hell exists?
nope
Does positron have a negative charge?
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.A POSITron has a POSITive charge, hence the name.

Is there such a thing as Atlantis?
Proof of it exists only in Plato's writings.
What is the antimatter version of an electron?
positron
Where is the Rabbit-Proof Fence in Australia?
The Rabbit-proof fence exists under various names in Western Australia
Where is bigfoot in Ohio?
There is really no absolute proof that Bigfoot even exists.
What is the anti-matter equivalent of an electron?
No. The antiparticle for the proton is called antiproton. The antiparticle for the electron is called antielectron, also known as positron.
