“…The situation is completely different when pairing is included. In this case, the main contribution to the scissors mode energy comes from the pairing interaction, E sc is not proportional to δ, and the deformation dependence of B(M1) sc becomes quadratic in excellent agreement with QRPA calculations and experimental data [2,12,13,14,15,16,17,18].…”

“…This prediction is supported by calculations in the frame of Quasiparticle-Phonon Nuclear Model (QPNM), which also predicts remarkable M 1 strength below the conventional energy interval. A short outline of QPNM together with calculation details can be found in the papers [19,20].…”

“…FIG.5: Comparison of the summed B(M 1) values for SR in160,162,164 Dy from the present WFM theory, the QPNM[19,20] and Gogny QRPA[18] calculations with the experimental values from the NRF[17], photoneutron measurements (Oslo)[18] and from multistepcascade (MSC) measurements of γ decay following neutron capture[21]. Panel (a) -averaging energy intervals are 2 − 4 MeV for WFM, QPNM and NRF; 0 − 3.5 MeV for QRPA; 0−10 MeV for Oslo and MSC, (b) -averaging interval is 2.7 − 3.7 MeV.…”

The fine structure of the scissors mode is investigated within the Time Dependent Hartree-Fock-Bogoliubov (TDHFB) approach. The solution of TDHFB equations by the Wigner Function Moments (WFM) method predicts a splitting of the scissors mode into three intermingled branches. Together with the conventional scissors mode two new modes arise due to spin degrees of freedom. They generate significant M 1 strength below the conventional energy range. The results of calculations of scissors resonances in Rare Earths and Actinides by WFM and QPNM methods are compared with experimental data. A remarkable coherence of both methods together with experimental data is observed.

“…Vibrational states and gamma-ray transition rates in welldeformed doubly even nuclei have been calculated within the quasiparticle-phonon nuclear model (QPNM) [12,13,14,15,16]. The QPNM is used for a microscopic description of the low-spin, small-amplitude vibrational states in spherical nuclei not far from closed shells and well-deformed nuclei.…”
