Possible violation of the Gallagher-Moszkowski rule in the sup(160,162)Tm isotopes

Analysis of the experimental data on the energy levels and E2, E1 and M1 transition probabilities in the low-lying spectrum on odd-odd sup(160,162)Tm isotopes has been performed in the framework of the ''two-quasiparticle+rotor'' model. The assignment of the 5/2[402]sub(p-)3/2[521]sub(n) configuration (violating the Gallagher-Moszkowski rule) to the ground state of both nuclei appears to improve significantly agreement of the theoretical f-forbidden E1 transition probabilities with the experimental ones. Interpretation of low-lying levels in both studied nuclei, which improve the description of experimental data in comparison with previous papers, is proposed. The proposed way of theoretical interpretation makes possible extracting the information from experiment about the intrinsic modes of nuclear motion and provides in such a Way the data for testing the nuclear models of odd-odd nuclei
