Abstract

α decay of 271−294115 superheavy nuclei is studied using the Coulomb and proximity potential model for deformed nuclei (CPPMDN). The predicted α half-lives of 287115 and 288115 nuclei and their decay products are in good agreement with experimental values. Comparison of α and spontaneous fission half-lives predicts four-α chains and three-α chains, respectively, from 287115 and 288115 nuclei and are in agreement with experimental observation. Our study predicts two-α chains from 273,274,289115, three-α chains from 275115, and four-α chains consistently from 284,285,286115 nuclei. These observations will be useful for further experimental investigation in this region.
