Studies of Deuteron Breakup Reactions in Deuteron–Deuteron Collisions at 160 MeV with BINA

Abstract

A rich set of differential cross section of the three-body 2H(d,dp)n breakup reaction at 160MeV deuteron beam energy has been measured over a large range of the available phase space. The experiment was performed at KVI in Groningen, the Netherlands, using the BINA detector. The cross-section data for the breakup reaction have been normalized to the simultaneously measured 2H(d,d)2H elastic scattering cross section. The breakup cross sections obtained for 147 kinematically complete configurations near the quasifree scattering kinematics are compared to the recent approximate calculations for the three-cluster breakup in deuteron–deuteron collisions. The cross sections for 294 kinematic configurations of the quasi-free scattering regime, for which no theoretical calculations exist, are also presented. Besides the three-body breakup, semiinclusive energy distributions for the four-body 2H(d,pp)nn breakup are reported.
