Medium modifications of the nucleon-deuteron break-up cross section in the Faddeev approach

The three-nucleon scattering problem in a nuclear medium is considered within the Faddeev technique. In particular the deuteron break-up cross section that governs the formation and the break-up reactions of deuterons (NNN ↔ Nd) in a nuclear environment is calculated at finite temperatures and densities. A significant enhancement of the in-medium break-up cross section with increasing density has been found.
