METHOD FOR IDENTIFICATION liner shotguns USING neutron activation analysis

摘要

1.method of identification on the cartridge case smooth bore u043eu0440u0443u0436u0438u00a0 using neutron activation analysis, characterized by an internal u043fu043eu0432u0435u0440u0445u043du043eu0441u0442 it u043fu043eu043au0440u044bu0442u0438u00a0 compression marks, u0441u043eu0441u0442u043eu00a0u0449u0435u0435 half-life periods of three metals, radioactive elements which u0441u043eu0441u0442u0430u0432u043bu00a0u044eu0442 not less than 5 days.with the introduction of the trace elements in coating provides the outer surface of the shell in the shot, followed by the definition of u043au0430u0447u0435u0441u0442u0432u0435u043d and the quantitative composition of u0432u043du0435u0434u0440u0438u0432u0448u0438u0445u0441u00a0 elements using neutron activation analysis of the surface of the shell.;2. method for u043eu0442u043bu0438u0447u0430u044eu0449u0438u0439u0441u00a0 1, so that the pre u043eu043fu0440u0435u0434u0435u043bu00a0u044eu0442 neutron activation response of the shells is known to be used in the implementation of the shot of the rdr u0443u0436u0438u00a0, u0438u0441u043fu043eu043bu044cu0437u0443u00a0 result as a control.
