The break-up reaction p 0 + d → p 1 + p 2+ n at E0 = 16 MeV

Abstract

The break-up reaction p 0 + d → p 1 + p 2 + n has been studied at E 0 = 16 MeV in kinematically complete p 1-p 2 coincidence experiments with special regard to n-p final-state interactions (f.s.i.) and p 1-p 2 quasifree scattering (q.f.s.). The absolute differential cross section has been measured for n-p f.s.i. c.m. production angles from 60° to 140° and for four pairs of angles with strong contributions due to q.f.s. Calculations with separable nucleon-nucleon potentials based on the Faddeev equations are in good agreement with the data obtained. In general, the shape of the experimental differential cross section is well reproduced. Discrepancies of up to 30 % in the worst cases arise between the absolute values of the theoretical predictions and the experimental data.
