The energy gap in infinite nuclei is shown to vanish at the normal density. The mechanism which produces an energy gap of a reasonable value in finite nuclei is clarified. By using the reaction matrix as the effective interaction, it is stressed that the localization of the wave function in finite nuclei plays an essential role. In order to confirm the results of the qualitative discussion, a calculation of the energy gap is made directly from the free nucleon-nucleon interaction without using the reaction matrix formalism. Three-range Gaussian potentials including a repulsive soft core are adopted as the free nucleon-nucleon interaction; these do not give an energy gap in the case of infinite nuclear matter. A gap equation similar to the usual one is derived by overcoming some difficulties and complications which occur when we treat both the discrete and the continuum states. The calculated results show that the reasonable value of a few MeV for the energy gap is certainly obtained in the case of finite nuclei.
