RENORMALIZATION OF G-BOSON EFFECTS UNDER WEAK-COUPLING CONDITION

An approach based on purturbation theory is proposed to renormalize g- boson effects for sdgIBM system, which modifies that presented earlier by Druce et al. The weak coupling condition as the usage premise of t he two approaches is proved to be satisfied. Two renomalization spectr a are calculated for comparison and analyses. Results show that the g- boson effects are renormalized more completely by the approah proposed in this paper.
