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.

The effective liquid drop model (ELDM) is used to explore the one proton radioactivity of all possible Dysprosium isotopes, and the molecular phase of the di-nuclear system is used to investigate the possible barriers limiting one proton emission. The mass excess values are obtained from [Chin. Phys. C 45 (2021) 030003]. The WKB integral is used to evaluate the penetration probability. The half-lives of proton decay are compared to those of other decay modes. The decay chains of [Formula: see text]Dy are predicted. The detailed investigations of [Formula: see text]Dy show proton radioactivity when [Formula: see text]Tb is converted to [Formula: see text]Gd with the half-life of order of nanoseconds. Further, these identified proton emitters may find to be useful in the field of diagnosis and radiotherapy.
