ON THE SURVIVAL OF THE SD-PAIR SHELL MODEL UNDER PSEUDO-SPIN TRANSFORMATION

Abstract

The pseudo-spin concept and the SD-pair shell model provide for tractable truncations of large model spaces. We tested the compatibility of these concepts, and hence the applicability of the SD-pair shell model to its pseudo SD-pair analog, for the (1h9/2 2f7/2 2f5/2 3p3/2 3p1/2)8 system. The validity of the SD-pair concept is found to survive under pseudo-spin transformation.
