Measurement of the 70Ge(n,¿) cross section up to 300 keV at the CERN n_TOF facility

Neutron capture data on intermediate mass nuclei are of key importance to nucleosynthesis in the weakcomponent of the slow neutron capture processes, which occurs in massive stars. The (n,¿) cross section on70Ge, which is mainly produced in thesprocess, was measured at the neutron time-of-flight fac...
