Erratum: Astrophysically important 26 Si states studied with the ( 3 He, n) reaction and the 25 Al( p, γ ) 26 Si reaction rates in explosive hydrogen burning environments [Phys. Rev. C 70, 065805 (2004)]

A recent study of nuclear level densities for 20рAр70 found evidence that the level densities for nuclei off the stability line were lower than those for nearby nuclei on the stability line. This analysis has been extended to cover the mass range 20рAр110 with results that support the original conclusions. As part of the study, the variations with energy and mass number of the parity ratio and spin cutoff parameter are examined.

The energy spectra of neutrons, protons, and α-particles have been measured from the d+ 59 Co and 3 He+ 58 Fe reactions leading to the same compound nucleus, 61 Ni. The experimental cross sections have been compared to Hauser-Feshbach model calculations using different input level density models. None of them have been found to agree with experiment. It manifests the serious problem with available level density parameterizations especially those based on neutron resonance spacings and density of discrete levels. New level densities and corresponding Fermi-gas parameters have been obtained for reaction product nuclei such as 60 Ni, 60 Co, and 57 Fe.
