Structure of the *b-Decay Function / I.N.Izosimov. – Text : electronic // Chinese Physics C. – 2026. – Vol. 50, No. 6. – P. 062001. – URL: https://doi.org/10.1088/1674-1137/ae4e15. – Bibliogr.: 73.
An analysis of experimental data on measurements of the resonant and fine structure of the β-decay strength function S&sub(*b)(E) in spherical, transitional, deformed, and halo nuclei has been conducted. Modern nuclear spectroscopy methods have revealed peak splitting in S&sub(*b)(E) for Gamow–Teller (GT) type β-transitions, caused by nuclear deformation. The resonant structure of S&sub(*b)(E) for first-forbidden (FF) β-transitions has been experimentally confirmed in both spherical and deformed nuclei. It is shown that at certain nuclear excitation energies, FF β-transitions can reach intensities comparable to those of GT β-transitions. An analysis of the evolution of the energy difference (E&sub(GTR)-E&sub(IAR)) between the GT resonance (GTR) and isobaric analog resonance (IAR) with increasing neutron excess in nuclei has been performed. A region exhibiting Wigner spin–isospin SU(4) symmetry has been predicted.
