Few-nucleon system dynamics studied via deuteron-deuteron collisions at 160 MeV

Abstract

Four nucleon scattering at intermediate energies provides unique opportunities to study effects of the two key ingredients of the nuclear dynamics, the nucleon-nucleon P-wave (NNP-wave) and the three-nucleon force (3NF). This is possible only with systematic and precise data, in conjunction with exact theoretical calculations. Using the BINA detector at KVI Groningen, the Netherlands, a rich set of differential cross section of the ^{2}2H(d,dp)n breakup reaction at 160 MeV deuteron beam energy has been measured. Besides the three-body breakup, also cross sections of the ^{2}2H(d, ^{3}3He)n proton transfer reaction have been obtained. The data are compared to the recent calculations for the three-cluster breakup.
