In an alpha -decay, the kinetic energy of alpha particle is 48 (MeV) and Q value of the reaction is 50MeV . The mass number of the mother nucleus is (Assume that daughter nucleus is in ground state).

The alpha -decay of nucleus X^(230) is accompanied by emission of two groups of alpha- particles-one group having alpha- particles of kinetic energy 6.7MeV and other having alpha -particles of kinetic energy 5.2 MeV. Following the emission of these particles the daugheter muclei are found in ground and exiceted states. find the energy of gamma photon. that is subsequenctly emitted by de-exictation of the excited daughter nuclei. Assume that nuclei of X^(230) are at rest.
