摘要：

alpha decay of(271-294)115 superheavy nuclei is studied using the Coulomb and proximity potential model for deformed nuclei (CPPMDN). The predicted alpha half-lives of (287)115 and (288)115 nuclei and their decay products are in good agreement with experimental values. Comparison of alpha and spontaneous fission half-lives predicts four-alpha chains and three-alpha chains, respectively, from (287)115 and (288)115 nuclei and are in agreement with experimental observation. Our study predicts two-alpha chains from (273,274,289)115, three-alpha chains from (275)115, and four-alpha chains consistently from (284,285,286)115 nuclei. These observations will be useful for further experimental investigation in this region.
