Microscopic description of the scissors mode in odd-mass heavy deformed nuclei
Carlos E. Vargas, Jorge G. Hirsch, Jerry P. Draayer
Pseudo-SU(3) shell-model results are reported for M1 excitation strengths in 157-Gd, 163-Dy and 169-Tm in the energy range between 2 and 4 MeV. Non-zero pseudo-spin couplings betwe…
Excited bands in odd-mass rare-earth nuclei
C. E. Vargas, J. G. Hirsch, J. P. Draayer
Normal parity bands are studied in 157Gd, 163Dy and 169Tm using the pseudo SU(3) shell model. Energies and B(E2) transition strengths of states belonging to six low-lying rotationa…
A study of randomness, correlations and collectivity in the nuclear shell model
V. Velazquez, J. G. Hirsch, A. Frank +1
A variable combination of realistic and random two-body interactions allows the study of collective properties, such as the energy spectra and B(E2) transition strengths in 44Ti, 4…
The Pairing interaction in nuclei: comparison between exact and approximate treatments
J. Dukelsky, G. G. Dussel, J. G. Hirsch +1
As a model for a deformed nucleus the many level pairing model (picket fence model with ~100 levels) is considered in four approximations and compared to the exact solution given b…
