NEUTRON-CAPTURE RESONANCES IN SN-116, SN-118, AND SN-120

The neutron capture cross sections of Sn-116, Sn-118, and Sn-120, whic h were determined recently with the Karlsruhe 4 pi BaF2 detector, have been reanalyzed at low energies. Resonance parameters were extracted by means of a shape analysis program, thus allowing a more reliable de termination of the averaged cross sections below 20 keV. This study co nfirms the previously reported stellar cross sections. Accordingly, th e results of the s-process studies based on these data remain unchange d.
