Radioactive decay properties of superheavy element Z= 119

Abstract

Within the macroscopic approach, investigation of different decay modes such as alpha decay,cluster decay (12C to 40Ca), HPR, (58Ni to 85Rb) and SF half-lives are investigated in detail in the SHE, Z=119. The decay energies, penetration probability and different decay half-lives in the isotopes of SHN 290−303119 are evaluated. Both 12C and 40Ar cluster emissions reveal shorter half-lives when compared to other cluster emissions. Furthermore, 85Rb heavy particle emission from the SHN 290−303119 discloses shorter half-lives compared to other heavy particle emissions. From the comparison of different decay half-lives, it is observed that 85Rb HPR is dominant in the region 290−299119, alpha decay is dominant for the 300−302119 and SF half-lives are predominant in 303119 nuclei. Hence, the prediction of decay modes and decay path in the SHE, Z=119 are helpful in the identification of experimentally synthesized SHE.
