Abstract

This article focuses on the investigation of heavy particle radioactivity (HPR) and other decay modes—spontaneous fission (SF), alpha decay, and beta decay—in superheavy elements (SHE) with atomic numbers 104 to 126. Using the modified generalised liquid drop model (MGLDM) and Coulomb and proximity potential model (CPPM), the study evaluates Q-values and half-lives of cluster decays, finding that MGLDM aligns more closely with experimental data. The research identifies dominant HPR emissions such as ^86Kr, ^94Zr, ^91Y, and ^96Mo in SHE with Z = 118, 122–124, and 126, and predicts decay chains that predominantly end in stable lead (Pb) nuclei. These findings have potential implications for nuclear astrophysics, particularly in understanding element formation in supernovae and galactic spectra.
