The structure of β-vibrational states populated by α-decay in the 232U-nucleus

Calculations of α-decay hindrance factors are performed for the 232U-nucleus. Within the framework of the pairing vibrations model a strong disagreement is obtained in both hindrance factors and β-vibrational state energies with experimental data and values obtained in other models. It is shown that only the model with pairing, quadrupole and spin-quadrupole effective forces can describe both the energies and the alpha hindrance factors for β-states in the 232U-nucleus.
