`^32P` beta-decays to `^32S`.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 `^32P=31.974 u` and that of `^32S=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` .
