Question

34 the nucleus 235 92Y initially at rest decays into 231 90 X by emitting an a particle 235 231 4 92 90 2 Y X He energy The binding energies per nucleon the daughter nucleus and a particle are 7 8 MeV 7 835 MeV and 7 07 Mev Respectively Assuming the daughter nucleus to be formed in the unexcited state and neglecting its share in the energy of the reaction find the speed of the emitted a particle Mass of a particle 6 68x10 27 kg
