摘要：

We report total cross sections for the F-19(alpha ,n)Na-22 and Ne-22(p,n)Na-22 reactions from threshold to 3.1 and 5.4 MeV, respectively. The absolute efficiency of the 4 pi 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 for F-19(alpha ,n)Na-22 and between 0.1 and 10 GK for Ne-22(p,n)Na-22.
