Investigation of radioactive decay modes of oganesson isotopes

We calculate the [Formula: see text]-decay and spontaneous fission half-lives of the artificially synthesized superheavy isotopes of oganesson (Og, Z = 118), which is recognized as the last element of the periodic table, in order to determine the decay modes of Og isotopes. For the [Formula: see text]-decay calculations, the Coulomb and Proximity Potential Model (CPPM) is employed together with the Universal Decay Law (UDL). In addition, the modified form of the UDL proposed by Soylu and Qi, whi
