“…The isovector SDI strength A 1 was fitted to reproduce the excitation energy of the 2 + 1 state in 134 Te. We have also considered an alternative set of proton particle energies suitable for A = 150 based on the assumption of a subshell closure at Z = 64 [35][36][37][38][39][40]. They were extracted from the excitation spectrum of 147 Tb.…”

. (2016). Occupation probabilities of single particle levels using the microscopic interacting boson model: Application to some nuclei of interest in neutrinoless double-β decay. Physical Review C, 94 (3), 034320. doi:10.1103/PhysRevC.94.034320 2016 PHYSICAL REVIEW C 94, 034320 (2016) Occupation probabilities of single particle levels using the microscopic interacting boson model:Application to some nuclei of interest in neutrinoless double-β decay We have developed a new method to calculate the occupancies of single particle levels in atomic nuclei. This method has been developed in the context of the microscopic interacting boson model, in which neutron and proton degrees of freedom are treated explicitly. The energies of the single particle levels constitute a very important input for the calculation of the occupancies in this method. In principle these energies can be considered as input parameters that can be fitted to reproduce the experimental occupancies. Instead of fitting, in this study we have extracted the single particle energies from experimental data on nuclei with a particle more or one particle less than a shell closure. We provide the sets of these single particle energies suitable for several major shells and apply our method to calculate the occupancies of several nuclei of interest in neutrinoless double-β decay using these sets. Our results are compared with other theoretical calculations and experimental occupancies, when available.

“…The result of a g-factor measurement in Tokyo [-5] was published last year, and quite recent measurements at Orsay and Strasbourg with heavy ion beams [-6] established the much higher yrast states up to 75/2-at 13.2 MeV. 149Tb was also investigated with the (3He, d) transfer reaction [7] that populated the 5 single-proton states of the 50 to 82 shell, and a recent study of 149Dy /%decay [-8] gave detailed information on the 149Tb excitations below 2.2 MeV with spins up to 11/2. In concurrent investigations of high-spin isomer decays of N=83 isotones [9,10] it was found that the 0.5-s 27/2-3qp isomer in 149Dy has a weak Gamow-Teller/~-decay branch which selectively populates highlying non-yrast states in 149Tb. These results crucially relate to our present in-beam data, and we will discuss them in detail below.…”

Yrast-and above-yrast states in 149Tb were investigated in (c~, 6n) and (TLi, 2n) in-beam 7-ray experiments. The yrast 7-ray cascade strongly populates three-valenceparticle states involving the hx 1/2 proton and the f7/2, h9/z, or i13/2 neutron orbitals, as well as the high-spin levels formed by the couplings of the three 149Tb valence particles, to the low-lying 146Gd octupole phonon and to higher-lying proton particle-hole core excitations. The data give the (~ h 11/2 v i13/2)12 -attraction free of octupole contributions as -631 keV. The shell model with empirical two-particle-and particle-phonon residual interactions gives an excellent quantitative description of the 149Tb energy levels. It is noted that the observed highspin members of the 7chll/2vh9/zvfT/2 configuration closely resemble the lowest symmetric and mixed-symmetry representations of the $3 permutation group.
