Experimental data obtained by measuring the fine structure of the strength function S{sub {beta}}(E) in spherical and deformed nuclei were analyzed. The use of modern nuclear-spectroscopy methods made it possible to reveal the nuclear-deformation-induced splitting of peaks in S{sub {beta}} (E) for transitions of the Gamow-Teller type. For first-forbidden transitions, the resonance nature of S{sub {beta}} (E) was proven experimentally both for spherical and for deformed nuclei. It is shown that, at some values of the excitation energy, the intensity of first-forbidden transitions in nuclei can be commensurate with the intensity of Gamow-Teller transitions.
