The s-process between A = 120 and 124 - Signature of neutron density and temperature in red giants

To improve the s-process analysis in the mass range 120-130, additional cross section measurements were carried out on Sn-120, Sb-121, Sb-123, and Te-128. Improved calculations are also included for the cross sections of the branch point nuclei Sn-121 and Sb-122. Based on the new results, the astrophysical aspects are discussed with emphasis on detailed s-process analyses using the classical approach and a schematic stellar model, including also a first decomposition of the p-process abundance at A = 122.
