J. Escher et Jp. Draayer, PAIRING-PLUS-QUADRUPOLE MODEL AND NUCLEAR-DEFORMATION - THE ROLE OF THE SPIN-ORBIT INTERACTION, Revista Mexicana de Fisica, 42, 1996, pp. 59-72
The pairing-plus-quadrupole model, realized in the framework of the El
liott SU(3) scheme, is used to study the combined effects of the quadr
upole-quadrupole, pairing, and spinorbit interactions on ground state
shapes of nuclear systems. Representation mixing induced by the symmet
ry-breaking pairing and spin-orbit forces is shown to soften the defor
mation. The angular momentum dependence of the results is discussed.
