Abstract

The cross sections of51V(α, n)54Mn and 51V(α, p)54Cr have been measured in the bombarding-energy ranges of 2.00-9.49 MeV and 5.755-9.590 MeV, respectively. The cross sections, together with cross sections of 54Cr(p, γ)55Mn and 54Cr(p, n)54Mn taken from the literature, have been compared with the results of statistical-model calculations. Thermonuclear reaction rates at temperatures appropriate to silicon burning in massive stars and supernovae have been calculated for both reactions.
