Study of the d(d, p) ³H and d(d, n) ³He processes at low energies

Abstract

The processes d(d, p) 3H and d(d, n) 3 He at energies of interest for energy production and for big-bang nucleosynthesis are studied using the hyperspherical harmonic method. The interactions include modern two- and three-nucleon interactions, derived in chiral effective field theory. We report results for the astrophysical S-factor and the quintet suppression factor.
