Abstract

We report total cross sections for the 19F(α,n)22Na and 22Ne(p,n)22Na reactions from threshold to 3.1 and 5.4 MeV, respectively. The absolute efficiency of the 4π neutron detector was determined by Monte Carlo calculations and validated using two standard sources and two nuclear reactions. Cross sections for the inverse reactions (between ground states) have been calculated using the principle of detailed balance, and reaction rates for both the reactions and their inverses determined for temperatures between 0.01 and 10 GK for19F(α,n)22Na and between 0.1 and 10 GK for 22Ne(p,n)22Na.
