Explain with the help of a nuclear reaction in each of the following cases, how the neutron to proton ratio change during (i) alpha - decay (ii) beta - decay.
An artifical radioactive decay series begins with unstable ._94 ^241 Pu . The stable nuclide obtained after eight alpha- decays and five beta^+ - decays is.
Calculate the amount of energy released during the alpha -decay of ._(92)^(238)Urarr_(90)^(234)Th+._(2)^(4)He Given: atomic mass of ._(92)^(238)U=238.05079 u , atomic mass of ._(90)^(234)Th=234.04363 u , atomic mass ._(2)^(4)He=4.00260u , 1u=931.5 MeV//c^(2) . Is this decay spontaneous?Give reason.
During a beta decay
A nuclide A undergoes alpha -decay and another nuclide B undergoed beta -decay. Then,
A nuclide A undergoes alpha -decay and another nuclides B undergoes beta -decay
