R-matrix evaluations of (alpha,n)

A brief overview of the R-matrix evaluation method implemented in EDAf90 that emphasizes the relativistic model parametrization, polarization capabilities, and computational capabilities. We will review existing evaluations for (alpha,n) on material targets n, 1H, 2H, 3H, 3He, 6Li, 7Li, 11B (time permitting) and discuss recent activity on 13C in the 17O system analysis.
