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.
超重元素Z= 119的放射性衰变性质
在宏观方法中,详细研究了不同的衰变模式,如α衰变、团簇衰变(12C至40Ca)、HPR、(58Ni至85Rb)和SF半衰期。计算了shn290 ~ 303119同位素的衰变能、穿透概率和不同的衰变半衰期。与其他簇辐射相比,12C和40Ar簇辐射的半衰期都较短。此外,来自SHN 290−303119的85Rb重粒子发射比其他重粒子发射的半衰期更短。通过对不同衰变半衰期的比较,发现85Rb HPR在290 ~ 299119区占优势,α衰变在300 ~ 302119区占优势,SF半衰期在303119区占优势。因此,对Z=119的SHE的衰变模式和衰变路径的预测有助于实验合成SHE的识别。
