`P^32` beta-decays to `S^32`.Find the sum of the energy of the antineutrino and the kinetic energy of the `beta`-particle. Neglect the recoil of the daughter nucleus. Atomic mass of `P^32=31.974 u` and that of `S^32=31.972 u`.

Text Solution

Verified by Experts

The correct Answer is:
A
`p^(32) rarr S^(32) + _1v^0 + _(-1)beta^0`
Energy of antineutrino and `beta-particle`
`= (31.974 - 31.972)u`
`= 0.002u`
`=0.002 xx 931= 11.862 MeV` .

The beta -decay process, discovered around 1900 , is basically the decay of a neutron (n) , In the laboratory, a proton (p) and an electron (e^(-)) are observed as the decay products of the neutron. Therefore, considering the decay of a neutron as a tro-body dcay process, it was observed that the electron kinetic energy has a continuous spectrum. Considering a three-body decay process i.e., n rarr p + e^(-)+overset(-)v_(e ) , around 1930 , Pauli explained the observed electron energy spectrum. Assuming the anti-neutrino (overset(-)V_(e )) to be massless and possessing negligible energy, and neutron to be at rest, momentum and energy conservation principles are applied. From this calculation, the maximum kinetic energy of the electron is 0.8xx10^(6)eV . The kinetic energy carried by the proton is only the recoil energy. If the anti-neutrino has a mass of 3eV//c^(2) (where c is the speed of light) instead of zero mass, what should be the range of the kinetic energy, K of the electron?

The beta - decay process , discovered around 1900 , is basically the decay of a neutron n . In the laboratory , a proton p and an electron e^(bar) are observed as the decay product of neutron.
