Ab initio four-body calculation of n-3He, p-3H, and d-d scattering

Abstract

Four-body equations in momentum space are solved for neutron-$\He$, proton-$\Hh$, and deuteron-deuteron scattering; all three reactions are coupled. The Coulomb interaction between the protons is included using the screening and renormalization approach as it was recently done for proton-deuteron and proton-$\He$ scattering. Realistic interactions are used between nucleon pairs. For the first time fully converged results for the observables pertaining to the six different elastic and transfer reactions are obtained and compared with experimental data.
