Exp 55 MN(P, gamma ) exp 56 Fe and exp 55 MN(P,N) exp 55 Fe Cross Sections

摘要

The cross section of the reaction exp 55 Mn(p, gamma ) exp 56 Fe has been measured in the energy range 0.80 - 2.04 MeV and of the reaction exp 55 Mn(p,n) exp 55 Fe from threshold to 2.04 MeV. Statistical-model calculations reproduce the (p,n) cross section to within a factor 1.4, but with the (p, gamma ) reaction they fail by a factor >2 over a significant part of the energy range. Thermonuclear reaction rates are calculated from the data for temperatures in the range (1-5) x 10 exp 9 K. (Atomindex citation 14:718877)
