Abstract

As an alternative to Wigner's spin-isospin SU(4) symmetry, known to be broken in heavier nuclei, a pseudo-SU(4) symmetry is proposed which follows from the combined invariance in pseudospin and isospin. The pseudo-SU(4) scheme is tested in N,Z>28 nuclei, and its consequences with regard to Gamow-Teller β decay are pointed out.
