Evaluation of Resonance Strengths and Reaction Rates of 22Ne (p, gamma) 23Na Nuclear Reaction at Thermonuclear Energies

At thermal energies near stellar conditions, nuclear reactions are sensitive to resonance strengths of the reaction cross-section. In this paper, were evaluated numerically by means rate calculations using a written Matlab code, at interest in reactions. The results compared with standard before and after application statistical analyses, select best parameters that made theoretical as close possible values. Fitting was for different temperature ranges up 10 GK, 0.6 GK 0.25 GK. showed range becomes narrower, more error is added strengths. A proper strength value based on most recent measured one suggested difference least order magnitude can be solved numerical evaluation less than 650 keV.
