The measurements of the total neutron cross sections of the stable nuclide /sup 112/Sn and the radioactive nuclide /sup 113/Sn were carried out on the neutron spectrometer of the reactor SM-2. The cross sections were measured by the time-of-flight method with the neutron chopper located in the horizontal beam of the reactor. The parameters of the resonance levels were calculated by the form method based on the Breit-Wigner one-level formula; in the neutron-energy region above 150 eV, the areas method was used for the calculation. Energy dependence determinations for neutron transmission by /sup 112/Sn-enriched tin were made in the 0.02-600 eV range. The total resonance capture integral was calculated from the parameters obtained for the neutron resonances. Information on the accumulation of /sup 113/Sn was obtained via the change in concentration of the /sup 113/In product of electron capture. Four neutron levels in /sup 113/Sn were identified and their resonance parameters were calculated from measurements of energy dependences of neutron transport in the neutron-energy region up to 300 eV.
