Abstract
The Coulomb and proximity potential model for deformed nuclei (CPPMDN) is used to study the favored and unfavored decay of nuclei in the range ⩽ ⩽ from both the ground state (g.s.) and isomeric state (i.s.). The computed half-lives are in good agreement with experimental data. The standard deviation of half-life is found to be 0.44. Geiger-Nuttall (GN) plots for various parent isotopes are studied. It is found that all four types of transitions (g.s.→g.s., g.s.→i.s., i.s.→g.s., i.s.→i.s.) lie on a straight line. The isomeric state decay shows a behavior similar to that of the ground state and the nuclear structure of the isomeric states imitates that of the ground states. Some predictions are done for transition from both ground and isomeric states, which will be useful for future experiments.
