What is parity violation beta decay?
Parity violation beta decay is a type of nuclear decay process in which the weak nuclear force violates the conservation of parity. In regular beta decay, the emitted electron or positron has a preferred direction of emission, violating the principle of parity conservation. This phenomenon was first observed in the decay of cobalt-60 nuclei in a landmark experiment conducted in the 1950s by Wu and colleagues.
Why energy of beta particles is different in beta particle decay?
The energy of beta particles in beta decay is not fixed because it depends on the specific isotope and decay process involved. Beta decay can produce high-energy electrons and positrons through beta minus and beta plus decay, respectively. The energy of the beta particles is determined by the energy released during the decay process.
What type of nuclear decay produces energy instead of a particle?
Gamma decay produces energy in the form of gamma rays, which are high-energy electromagnetic radiation, instead of particles. Gamma decay occurs when an unstable atomic nucleus transitions to a lower energy state by releasing gamma rays.
Why do some researchers complain when the emission of a gamma particle is called gamma decay?
Because its not a decay process. Gamma is an emission of energy in the form of photons from the nucleus when the nucleus changes from one energy level to a lower energy level. It is true that this is often preceded by a decay event, such as alpha or beta, but it is a distinct, non decay, event.
What type of radioactive decay releases energy from the nucleus without a change of protons neutrons?
This is a gamma-decay.

Does the law of conservation of mass satisified in beta decay process?
The masses don't exactly balance. Instead, the energy of the whole system is balanced (remember mass and energy are related by the equation E = mc^2)
What is lost during radioactive decay?
Decay energy is the energy that has been freed during radioactive decay. When radioactive decay is ongoing it drops off some energy by means of discharging radiation.
Geothermal energy is caused by what type of decay?
It is Radioactive Decay.

How do you calculate the recoil energy of a daughter nucleus?
The conservation of energy tells us that energy before the collision equals energy the comes out of the system after the collision. In the case of a stationary target nuclei and a neutron beam we have as our initial energy Rest mass (E - mc2) of the nuclei and the particle in the beam. Kinetic energy of the nuclei and the neutron projectile. So the initial energy looks like KEn + mn*c2 + KEnuc + mnuc*c2 We note that the initial KE of the stationary nucleus is zero and omit this term. KEn + mn*c2 + mnuc*c2 Assuming neutron absorption (i.e. only 1 particle) all of the energies after the collision are described by KEnuc_f + mnic_f*c2 Use the principle of conservation of energy to set the two equal to one another. KEn + mn*c2 + mnuc*c2 = KEnuc_f + mnic_f*c2 Now solve for the final KE of the combined nuclei, KEnuc_f KEnuc_f = (KEn + mn*c2 + mnuc*c2) - (mnic_f*c2) This is the recoil energy.
What is the endpoint energy of beta particle?
The endpoint energy of a beta particle is the maximum kinetic energy it can have after being emitted in a beta decay process. This energy depends on the specific isotope undergoing decay, with different isotopes having different endpoint energies.
Why a free neutron does not decay into electron and positron?
What makes you think that it should decay precisely into an electron and a positron, rather than some other option?Anyway, in any such particle conversion, certain quantities must be conserved. Some of these conservation laws are strict (no exceptions are known to exist), some not (now and then there is an exception). For the proposed reaction, you should consider the following conservation laws:Conservation of mass/energy - the electron and the positron have much less mass than the neutron. This would not pose a significant problem, since they could move away from each other at a high speed - the missing mass/energy would be present in the form of kinetic energy. This indeed happens in some particle reactions.Conservation of momentu - no problem here, either.Conservation of electric charge - no problem here.Conservation of baryon number - this would NOT be conserved in your proposed reaction. Please note that this is not a strict conservation law; there are known violations. However, violating the baryon number in a particle conversion is quite uncommon. In this case, the neutron has a baryon number of +1, the proton (one of the decay products of the actual decay) also has a baryon number of +1, while electron + positron would have a baryon number of 0.
When an atom undergoes radioactive decay the energy released in the reaction comes from what?
The energy released in radioactive decay comes from the conversion of mass from the parent atom into energy according to Einstein's famous equation, E=mc². This energy is released in the form of radiation or kinetic energy of the decay products.
Does Gamma decay emits energy but no particles?
Yes, gamma decay emits energy in the form of gamma radiation, which is a high-energy electromagnetic wave. Gamma decay does not emit any particles, only electromagnetic radiation.
