Low energy 0+ excitations in 158Gd
Jorge G. Hirsch, Gabriela Popa, Shelly R. Lesher +3
High precision (p,t) studies of the deformed nucleus 158Gd allowed the observation of 13 excited 0+ states below an excitation energy of 3.1 MeV. This high density of low energy st…
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…
E2 and M1 strengths in heavy deformed nuclei
J. P. Draayer, G. Popa, J. G. Hirsch
Energy levels of the four lowest bands in 160,162,164Dy and 168Er, B(E2) transition strengths between the levels, and the B(M1) strength distribution of the ground state, all calcu…
Quasi-SU(3) truncation scheme for odd-even sd-shell nuclei
C. E. Vargas, J. G. Hirsch, J. P. Draayer
The quasi-SU(3) symmetry, as found in shell model calculations, refers to the dominance of the single particle plus quadrupole-quadrupole terms in the Hamiltonian used to describe…
QRPA and its extensions in a solvable model
Jorge G. Hirsch, Peter O. Hess, Osvaldo Civitarese
An exactly solvable model is introduced, which is equivalent to the exact shell-model treatment of protons and neutrons in a single j-shell for Fermi-type excitations. Exact energi…
Double beta decay in heavy deformed nuclei: what have we learned?
Jorge G. Hirsch
The pseudo SU(3) approach is used to describe low lying states and BE(2) intensities of rare earth and actinide nuclei which are double beta decay candidates. The double beta half…
