Abstract
The probable decay modes of actinide nuclei are \(\alpha\), \(\beta ^{+}\), \(\beta ^{-}\), proton decay and spontaneous fission. Dominant decay mode is identified by studying the competition between different decay modes. Half-lives of \(\alpha\), \(\beta ^{+}\), \(\beta ^{-}\), proton decay and spontaneous fission are studied using Coulomb and proximity potential model, modified generalized liquid drop model, effective liquid drop model and many semi-empirical relations. Half-lives produced by the present work are compared with that of experiments. By studying the different decay modes in the actinide region, we have identified two proton emitters, 92 new \(\beta ^{-}\) emitters, 74 new \(\alpha\)-emitters and 115 new spontaneous fissionable isotopes. These newly identified isotopes with different half-lives and decay energies find an important application in the field of medicine and industry
