Abstract
The neutron capture cross section of the -process branch nucleus affects the abundances of other nuclei in its region, especially and . In order to determine the energy-dependent neutron capture cross section in the astrophysical energy region, an experiment at the Los Alamos National Laboratory has been performed using the calorimetric array DANCE. The () cross section of has been determined relative to the well-known standard with uncertainties below 15%. Various resonances have been identified based on the value. Furthermore, the -process sensitivity of the new values was analyzed with the new network calculation tool NETZ.
