Description
Recent developments in four-nucleon scattering calculations will be presented. They are based on the Faddeev-Yakubovsky-type equations for transition operators that are solved in the momentum-space partial-wave representation. Their solution is complicated due to the presence of kernel singularities corresponding to open many-cluster channels. This difficulty becomes most evident if two-cluster channels are absent, as in 4n system, and at intermediate energies where breakup channels dominate. These cases will be discussed in detail.
