The single-particle (direct) mechanism of photonuclear reactions at high energies is considered on basis of the shell model. It is shown that the momentum distribution of the ground nuclear state which this model yields permits one to explain the shift forward of the photoproton momentum distribution peak and to obtain the correct value for the cross section of the reaction. (auth) l65O5 The excited state angular momenta and the multipolarities of the gamma transitions of Re/sup 187/ were obtained by measuring the angular correlation of the 552 to 134 kev, 480 to 134 kev and 72 to 134 kev gamma cascades. The value and M1 amplitudes of the radiation mixture, sigma /sup 2/ I(E2)/I(M1), corresponding to a gamma transition of 134 kev energy. The relative intensity of the 552 kev gamma line was determined. The internal conversion coefficient in the K shell was determined for the 134 kev gamma transition.
