Measurement of the 151Sm(n, γ) 152Sm cross section at n_TOF

Measurement of the 151Sm(n, γ) 152Sm cross section at n_TOF

The 151Sm(n, γ) 152Sm cross section, which is important for the interpretation of the 151Sm branching as an s-process thermometer, was measured from 1 eV up to 1 MeV at the innovative n_TOF facility at CERN. Based on these data, the Maxwellian-averaged cross section at k T = 30  keV is found to be 3...

Zusammenfassung:The 151Sm(n, γ) 152Sm cross section, which is important for the interpretation of the 151Sm branching as an s-process thermometer, was measured from 1 eV up to 1 MeV at the innovative n_TOF facility at CERN. Based on these data, the Maxwellian-averaged cross section at k T = 30  keV is found to be 3100±160 mb. This value can be used to constrain the thermodynamical conditions in Asymptotic Giant Branch (AGB) stars during He-shell burning.
