Neutron radiative capture cross sections, total cross sections, and average resonance parameters for the tin isotopes

Cross sections for radiative capture of neutrons in the energy region 20--450 keV and total cross sections from 20 to 1400 keV for the isotopes {sup 112,114--120,122,124}Sn and the natural mixture of tin have been measured by the time-of-flight method in the pulsed electrostatic accelerator EG-1 at our institute. The experimental data were analyzed in the framework of the statistical theory of nuclear reactions. New results were obtained on the neutron and radiative strength functions and also on the radii of potential scattering for {ital s} and {ital p} neutrons. The data on total cross sections and neutron strength functions were used to improve the parameters of the spherical optical model.
