摘要：

The origin and consequences of pseudospin symmetry in nuclear physics, which is exact for an oscillator potential with one-body orbit-orbit (nu(ll)) and spin-orbit (nu(ls)) interaction strengths in the ratio mu = 2-nu(ll)/nu(ls) = 0.5, are considered. Specifically, the nu(ls) almost-equal-to 4-nu(ll) condition is consistent with relativistic mean-field results and a pseudo LS coupling scheme. When deformation dominates, pseudospin extends to pseudo SU(3), which is applicable to superdeformation.
