Abstract
In the present paper we discuss the photodisintegration of the deuteron at about 20 Mev assuming the pion theoretical potential to make a check for the validity of the potential. A detailed calculation shows that the pion theoretical potential gives a qualitative agreement with experiments, especially in predicting a large isotropic part in the angular distribution of the final nucleons. This agreement is mainly attributed to the strong tensor force in the triplet P states and the possible hard-core-like repulsion in the singlet S state which was found in the previous analyses phenomenologically. It is to be noted, however, that there remain some ambiguities concerning the effects of the interaction moment at small inter-nucleon distances.
