Predictions on the alpha decay half lives of Superheavy nuclei with Z = 113 in the range 255 l.e. A l.e. 314

Abstract

An intense study of the alpha decay properties of the isotopes of superheavy element Z=113 have been performed within the Coulomb and proximity potential model for deformed nuclei (CPPMDN) within the wide range 255 l.e. A l.e. 314. The predicted alpha decay half lives of ${}^{278}$113 and ${}^{282}$113 and the alpha half lives of their decay products are in good agreement with the experimental data. 6{α) chains and 4α chains predicted respectively for ${}^{278}$113 and ${}^{282}$113 are in agreement with the experimental observation. Our study shows that the isotopes in the mass range 278 l.e. A l.e. 286 will survive fission and can be synthesized and detected in the laboratory via alpha decay. In our study, we have predicted 6α chains from ${}^{279}$113, 4α chains from ${}^{286}$113, 3α chains from ${}^{280,281,283}$113, 2α chains from ${}^{284}$113 and 1α chain from ${}^{285}$113. We hope that these predictions will be a guideline for future experimental investigations.
