Four-nucleon scattering: a new numerical approach

Abstract

The AGS equations are solved for n 3 H and p 3 He scattering including the Coulomb interaction. Comparison with previous work confirms the accuracy of the calculation and helps clarify a number of issues related to the n 3 H total cross section at the peak of the resonance region, as well as an A y deficiency in p 3 He. Calculations are fully converged in terms of NN partial waves and involve no uncontrolled approximations.
