Neutron capture resonances inSn116,Sn118, andSn120

The neutron capture cross sections of {sup 116}Sn, {sup 118}Sn, and {sup 120}Sn, which were determined recently with the Karlsruhe 4{pi} BaF{sub 2} detector, have been reanalyzed at low energies. Resonance parameters were extracted by means of a shape analysis program, thus allowing a more reliable determination of the averaged cross sections below 20 keV. This study confirms the previously reported stellar cross sections. Accordingly, the results of the {ital s}-process studies based on these data remain unchanged. {copyright} {ital 1996 The American Physical Society.}
