Abstract
We propose a new powerful method to construct a quasiparticle to be used in the rotating shell model (RSM) 1),2) for high-spin states in the yrast region. Use of the diabatic representation enables us to unambiguously specify individual rotational bands in which internal structure of the quasiparticle state vectors smoothly changes as functions of the rotational frequency w. Our approach is based on the selfconsistent collective-coordinate (SCC) method which is proposed by Marumori et al. ) as a microscopic theory of large-amplitude collective motions. We start from the time-dependent HartreeBogoliubov state vector of the following form:
