For liquid helium at the absolute zero temperature, a systematic calculation is performed so as to elucidate the inherences associated with the excitations in the roton region by solving the Girardeau-Arnowitt integral equation by the aid of a kind of Monte Carlo method in the scheme of the collective description. The whole frame work of the previous theory is kept unchanged, even if the Bogoliubov approximation, used in a previous paper, is replaced by the present pair approximation, because the previous theory was arranged, in advance, so as to incorporate the pair theory. For a suitable effective potential, the pair theory yields the negative chemical potential and the peak of the form factor in accord with the experimental result.
