Decay of proton, alpha and cluster; analytic expression for decay half-life; general decay law.

A general decay formula for the emission of charged particles from metastable nuclei is developed based on the basic phenomenon of resonances occurring in quantum scattering process under Coulomb-nuclear potential. It relates the half-lives of radioactive decays with the 𝑄 values of the outgoing elements with masses and charges of the nuclei involved in the decay. The relation is found to be a generalization of the Geiger–Nuttall law in 𝛼 radioactivity and explains well all the known emissions of charged particles including clusters, alpha and proton.
