In an

\alpha -

decay, the kinetic energy of

\alpha -

particle is 48 MeV and Q value of the reaction is 50 MeV. The mass number of the mother nucleus is [assume that daughter nucleus is in ground state]

View answer and explanation

Correct option: B

100

Option B (100) is correct because the mass number of the mother nucleus can be calculated using the kinetic energy of the alpha particle and the Q value of the reaction.
