A microscopic description of nuclear rotational motion in terms of solid harmonics expansion of the pair operator, 2

Solid harmonics expansion method is quantized in order to investigate the quantum effects beyond the Hartree-Bogoliubov theory of ''phase transition'' in nuclear rotational band. The lowest order in this method, through the Harris formula, is shown to be equivalent to the classical theory in the previous paper. The transition matrix elements within a rotational band can be shown in a simple formula. (auth.)
