Query: Studies of the Three-Body Breakup in Deuteron-Deuteron Collisions near
  the Quasi-Free Limit at 160 MeV   A set of differential cross section of the three-body $^{2}$H($d$,$dp$)$n$
breakup reaction at 160 MeV deuteron beam energy are presented for 147
kinematically complete configurations near the quasi-free scattering
kinematics. The experiment was performed at KVI in Groningen, the Netherlands
using the BINA detector. The cross-section data have been normalized to the
$^{2}$H($d$,$d$)$^{2}$H elastic scattering cross section. The data are compared
to the recent single-scattering approximation (SSA) calculations for
three-cluster breakup in deuteron-deuteron collisions. Confronting the SSA
predictions with the experimental data shows that SSA provides the correct
order of magnitude of the cross-section data. The studied energy is probably
too low to meet the SSA assumptions which prevents better accuracy of the
description.
