The currently available experimental data on the excitation functions for (p, n) reactions for 40 < A < 239 nuclei are analyzed. The proposed systematics includes three sections of the excitation function: equilibrium and two intervals covering pre-equilibrium processes. This allows the use of different parametrizations to obtain a closer fit between the predictions of the systematics and experimental data.

Nuclear reactions using proton beams and tin targets are studied in order to obtain antimony radionuclides. A new target system that includes on-line monitoring of target heating is used. To determine the parameters of proton beams, experimental studies on nuclear reactions are performed using Ti, Cu and stainless steel targets. Using modern model approximations, cross sections are determined for the formation of radionuclides 119Sb and 117Sb in the investigated nuclear reactions.

A resonance-like structure in the excitation function for elastic and inelastic 14C + 12C interactions is investigated. Angular distributions for the 14C(12C,10Be)16O reaction at center-of-mass energies of 21.1, 23.5, and 24.6 MeV are obtained. It is shown that the angular distribution at the maximum cross section corresponds to the 12+ resonance and the 10Be + 16O structure. The position of the level with an angular momentum of 10+ is predicted.

A method for describing the change in an electromagnetic field created by electrons generated by a narrow beam of gamma rays passing through a liquid medium is proposed. Results from calculations using this procedure can be employed in designing detectors for experiments in high-energy physics.
