Abstract
We show that the method based on the tensor coupling of an appropriate family of isovector excitation operators to the parent isospin multiplet can be used to advantage for the correct treatment of the isospin degree of freedom in nonisoscalar nuclei. This method is applicable to any isovector excitation operator and for parent states which need not be of the closed subshells type. As an illustration we apply it to the study of the Gamow-Teller transition strength in Zr90. © 1987 The American Physical Society.
