Abstract

The E1 astrophysical S factor for the C12(,)16O reaction is studied using R-matrix theory. The constraints on this quantity from the -particle spectrum following N16 decay are investigated with a set of pseudodata in an attempt to identify what additional information might be extracted from future measurements. The possibility of an experimental separation of the p- and f-wave particles is discussed. Additional precise measurements of the -delayed particles at total center-of-mass energies near 1.0 MeV and the (,) cross section at energies below and above previous measurements are particularly useful in constraining the S factor.
