摘要：

An intense study of the alpha decay properties of the isotopes on superheavy element with Z = 113 has been performed within the Coulomb and proximity potential model for deformed nuclei (CPPMDN) within the wide range 255 <= A <= 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 alpha chains and 4 alpha 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 <= A <= 286 will survive fission and can be synthesized and detected in the laboratory via alpha decay. In our study, we have predicted 6 alpha chains from (279)113, 4 alpha chains from (286)113, 3 alpha chains from (280,281,283)113, 2 alpha chains from (284)113 and 1 alpha chain from (285)113. We hope that these predictions will be a guideline for future experimental investigations. (C) 2016 Elsevier B.V. All rights reserved.
