Producing and application of thin solid targets for nuclear physics experiments

Abstract

Investigations of the structure of the atomic nucleus and the mechanisms of nuclear reactions at the present
stage of the development of physics impose increased requirements for nuclear targets, one of the most important components of the nuclear-physical experiment. Precision measurements of the differential cross sections of such reactions assume the use of thin, self-sustaining targets of enhanced purity with precisely defined elemental composition, thickness, and uniformity in the experiments. Experimentally in the laboratory of solid state physics of the Interdisciplinary Research Complex at the L.N. Gumilyov ENU named after was obtained thin solid targets 6 Li, 7 Li for subsequent applications in nuclear physics experiments
at the accelerator DC-60. The target, thickness, and manufacturing quality are extremely important elements for setting up experiments in nuclear physics. The paper describes a logically consistent technique for obtaining targets. Brief results of target irradiation with accelerated heavy carbon ions at different energies are given.
