L. Losano et H. Dias, QUASI-PARTICLE AND PHONON EXCITATIONS IN ODD-MASS N=83 ISOTONES, International journal of modern physics E, 5(1), 1996, pp. 153-173
The structure of low-lying states in odd-mass N = 83 isotones (135 les
s than or equal to A less than or equal to 151) is investigated in ter
ms of a model in which one neutron-quasiparticle is coupled to quadrup
olar and octupolar core-vibrations. Energy levels and spectroscopic fa
ctors are calculated and compared with experimental data. Nuclear Stru
cture: Te-135, Xe-137, Ba-139, Ce-141, Nd-143, Sm-145, Gd-147, Dy-149
and Er-151; calculated levels J, pi, and S. Quasiparticle-phonon coupl
ing model.
