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