Phys. Rev. C 66, 028802 (2002) [4 pages]Direct neutron capture cross sections of 62Ni in the s-process energy rangeSee Also: Erratum Received 12 June 2002; published 12 August 2002 Direct neutron capture on 62Ni is calculated in the DWBA and the Maxwellian averaged cross sections and astrophysical reaction rates in the energy range relevant for s-process nucleosynthesis are given. It is confirmed that the thermal value of the capture cross section contains a subthreshold resonance contribution. Contrary to previous investigations it is found that the capture at higher energies is dominated by p waves, thus leading to a considerably increased cross section at s-process energies and a modified energy dependence. © 2002 The American Physical Society URL:
