Neutron Capture Cross Section of Unstable 63Ni: Implications for Stellar Nucleosynthesis
The 63Niðn; Þ cross section has been measured for the first time at the neutron time-of-flight facility n_TOF at CERN from thermal neutron energies up to 200 keV. In total, capture kernels of 12 (new) resonances were determined. Maxwellian averaged cross sections were calculated for thermal energie...

| description | The 63Niðn; Þ cross section has been measured for the first time at the neutron time-of-flight facility
n_TOF at CERN from thermal neutron energies up to 200 keV. In total, capture kernels of 12 (new) resonances were determined. Maxwellian averaged cross sections were calculated for thermal energies from
kT 1⁄4 5–100 keV with uncertainties around 20%. Stellar model calculations for a 25M star show that the
new data have a significant effect on the s-process production of 63Cu, 64Ni, and 64Zn in massive stars,
allowing stronger constraints on the Cu yields from explosive nucleosynthesis in the subsequent supernova. |
