Theory of three- and four-body scattering — •Arnoldas Deltuva — Centro de Fisica Nuclear, University of Lisbon, Portugal

Few-body nuclear reactions are described in the framework of Alt, Grassberger, and Sandhas equations that are Faddeev-like integral equations. The Coulomb interaction between charged particles is included using the method of screening and renormalization. Momentum-space partial-wave basis is used for solving those equations. Results are obtained for proton-deuteron elastic scattering and breakup, electromagnetic disintegration of 3He, low-energy four-nucleon elastic and transfer reactions, and for direct nuclear reactions dominated by three-body degrees of freedom, e.g., d+4He, d+12C, and p+11Be.
