Cross sections of neutron radiative capture, total cross sections and mean resonance parameters for tin isotopes

Neutron capture cross sections in the 20-450 keV energy range and total cross sections from 20 to 1400 keV for 112,114-120,122,124Sn and natural tin have been measured by time-of-flight method at the pulsed electrostatic accelerator. The experimental data were analyzed in the framework of statistical theory of nuclear reactions and new results were obtained for neutron and radiative strength functions as well for potential scattering radii of s- and p-neutrons. The data on total cross sections and neuron srength functions were used for more accurate determination of the spherical optical model parameters
