The origin and consequences of pseudospin symmetry in nuclear physics, which is exact for an oscillator potential with one-body orbit-orbit (ll) and spin-orbit (ls) interaction strengths in the ratio ieq2ll/ls=0.5, are considered. Specifically, the ls 4ll 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. © 1992 The American Physical Society.
