Within the macroscopic approach, investigation of different decay modes such as alpha-decay, cluster-decay ([sup.12]C to [sup.40]Ca), heavy particle radioactivity (HPR) ([sup.58]Ni to [sup.85]Rb), and spontaneous fission (SF) half-lives are investigated in detail in the superheavy element (SHE), Z = 119. The decay energies, penetration probability, and different decay half-lives in the isotopes of synthesized superheavy nuclei (SHN) [sup.290-303]119 are evaluated. Both [sup.12]C and [sup.40]Ar cluster emissions reveal shorter half-lives when compared to other cluster emissions. Furthermore, [sup.85]Rb heavy particle emission from the SHN [sup.290-303]119 discloses shorter half-lives compared to other heavy particle emissions. From the comparison of different decay half-lives, it is observed that [sup.85]Rb HPR is dominant in the region [sup.290-299]119, alpha-decay is dominant for the [sup.300-302]119, and SF half-lives are predominant in [sup.303]119 nuclei. Hence, the prediction of decay modes and decay path in the SHE, Z = 119 are helpful in the identification of experimentally synthesized SHE. Key words: spontaneous fission, half-lives, alpha-decay, cluster-decay, heavy particle radioactivity, 1. Introduction Superheavy elements (SHE) are chemical elements with atomic numbers more than 103. They are beyond the actinides in the periodic table and are created by fusing the atomic [...]
