Abstract

The beta-decay strength function S β(E) is described within two approaches: numerical solution of equation of the theory of finite Fermi systems for the effective nuclear field and solution of these equations using the quasi-classical approximation. Calculations were carried out for the isotopes 71Ge and 127Xe. A comparison with experimental data showed their good accuracy. The resonance structure of the function S β(E) and the quenching-effect resulting from the effective charge of quasiparticles in the nucleus are discussed.
