The results obtained in experiments on uranium fission induced by 660- Mev protons and by 280-Mev pi /sup +/ mesons, which were carried out with the aid of nuclear emulsions, are reported. The angular correlation of the two protons which arise as a result of the interaction of a fast meson with a uranium nucleus was investigated. Analysis of data obtained leads to the conclusion that pi /sup +/- mesons capture occurs mainly as a result of interaction with a pair of nucleons. The measurements of the angular distributions of charged particles accompanying the uranium fission induced by high-energy protons were carried out. The data obtained show that such protons were emitted before the fission process. In the case of alpha particles some increase of probability of their emergence at large angles with respect to the direction of movement of fission fragments was observed. The various factors which can be responsible for such an effect are considered. (auth)
