Neutron capture cross section measurements of isotopes close to s-process branching -points are of fundamental importance for theunderstanding of this nucleosynthesis mechanism through which about 50\%of the elements heavier than iron are produced. We present in thiscontribution the results corresponding to the high resolutionmeasurement, for first time ever, of the 80Se(n, y) cross section, inwhich 98 resonances never measured before have been reported. As aconsequence, ten times more precise values for the MACS have beenobtained compared to previous accepted value adopted in theastrophysical KADoNiS data base.

Abstract
Neutron capture cross section measurements of isotopes close to s-process branching -points are of fundamental importance for theunderstanding of this nucleosynthesis mechanism through which about 50\%of the elements heavier than iron are produced. We present in thiscontribution the results corresponding to the high resolutionmeasurement, for first time ever, of the 80Se(n, y) cross section, inwhich 98 resonances never measured before have been reported. As aconsequence, ten times more precise values for the MACS have beenobtained compared to previous accepted value adopted in theastrophysical KADoNiS data base.File in questo prodotto:
