Abstract
This article explores a novel idea by proposing a unified semi-empirical formula for both alpha and beta decay in unstable nuclei. A key feature of this formula is its simplicity and ability to provide highly accurate decay information based solely on the fundamental properties of the parent nucleus. Another remarkable aspect is the large number of isotopes used to fit the formula, exceeding 2200. This extensive data set has significantly enhanced the formula's reliability. Additionally, we have included thorough comparisons between our results and those of other studies, which clearly demonstrate the higher performance of our formula. Even while our suggested formula is applicable to beta decay, the other formulae were particularly created for alpha decay.
