Empirical Systematics of Long-Range *a-Particle Emission Probabilities in Fission of Heavy and Superheavy Nuclei / N.S.Moiseev, N.V.Antonenko, G.G.Adamian. – Text : electronic // Physical Review C. – 2025. – Vol. 112, No. 4. – P. 044608. – URL: https://doi.org/10.1103/zmnk-gxs8.

The empirical systematics of long-range 𝛼-particle emission probabilities 𝑃&sub(LRA) are investigated in spontaneous and thermal-neutron-induced fission of heavy and superheavy nuclei. The correlations between 𝑃&sub(LRA) and various parameters, including the fissility 𝑍*2/𝐴, the linear combination of proton and mass numbers 4⁢𝑍−𝐴, and the release energy 𝑄&sub(𝛼) of 𝛼 decay are studied. A new semiempirical formula for 𝑃&sub(LRA), expressing it as a linear function of 𝑄&sub(𝛼), is proposed and its predictive power is compared with existing empirical and semiempirical formulas. The influence of experimental data uncertainties on the fitting results is shown. The values of 𝑃&sub(LRA) are predicted for neutron-deficient nuclei and superheavy nuclei. The approach was extended to describe the emission of light charged particles and clusters in both spontaneous and thermal-neutron-induced fission of heavy and superheavy nuclei.
