DOI: 10.1007/s00601-019-1501-4
Abstract: Faddeev–Yakubovsky four-nucleon scattering equations are derived including a three-body force. From the asymptotic form of the Yakubovsky-components we obtain scattering amplitudes of all outgoing channels in a direct manner. We present these equations in the… read more here.
