Sažetak
The 63Ni(n ; gamma) cross section has been measured for the rst time at the neutron time-of- flight facility n_TOF at CERN from thermal neutron energies up to 200 keV. In total 16 resonances couldbe identi ed and capture kernels be determined for 14 of these resonances. Maxwellian averaged cross sections were calculated for thermal energies from kT = 5 keV to 90 keV with uncertainties around 20%. Stellar model calculations for a 25 M star show that the new data have a significant effect on the s-process production of 63Cu, 64Ni, and 64Zn in massive stars.
