Three- and four-body nuclear reactions

Three- and four-body scattering is described in the framework of Faddeev-type integral
equations that are solved numerically using momentum-space partial-wave basis.
The Coulomb interaction between charged particles is included
using the screening and renormalization method.
The technique is applied to three-nucleon hadronic and electromagnetic
reactions, i.e., proton-deuteron (pd) elastic scattering
and breakup, pd radiative capture, electromagnetic disintegration
of 3He, and to four-nucleon elastic and transfer
reactions below three-body breakup threshold.
Furthermore, the method has been extended successfully to
elastic, transfer, and breakup reactions in three-body-like nuclear
systems. Examples are deuteron scattering on stable nuclei
and proton scattering on weakly bound two-body systems such as
one-neutron halo nuclei.
