A. Onoda et al., A STEP TOWARD LARGE-AMPLITUDE DESCRIPTION OF THE GROUND BAND AROUND BAND CROSSING, Progress of theoretical physics, 97(3), 1997, pp. 553-557
The possible occurrence of large-amplitude motion in the band-crossing
region is shown numerically for the ground rotational band. Calculati
ons are based on the formalism by means of the self-consistent collect
ive coordinate method.
