Partial Dynamical Symmetry in a Fermionic Many-Body System

Abstract

The concept of partial symmetry is introduced for an interacting fermion system. The associated Hamiltonians are shown to be closely related to a realistic nuclear quadrupole-quadrupole interaction. An application to ${}^{12}$C is presented.
