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 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 2H(d, 3He)n proton transfer reaction have been obtained. The data are compared to the recent calculations for the three-cluster breakup.

Report on Few-Nucleon System Dynamics Studiedvia Deuteron-Deuteron Collisions at 160 MeV by Ciepal et al. This paper shows results of 2H(d,dp)n experiments at 160MeV deuteron beam energy as carried out at KVI Groningen. The experiments aim to study particular effects which are best studied in 4-body systems (e.g. NN P-waves, aspects of 3NF) and compare to recent theory which has been able to make sophisticated calcualtions of such 4-body systems recently. The introduction includes a concise summary of the theoretical status of relevant calculations, highlighting the need for new experimental data. Section 2 gives a brief but sufficient description of the experimental setup, with a reference to a full desription The results section shows some sample results, including a comparison of the differential cross section to a range of theoretical calculations for a particular kinematic setup, showing pretty good agreement. Further details (e.g. as a function of angle) show up where the remaining discrepancies in the theoretical approaches lie in comparison with data. The paper then gives an interesting look forward to possible future experiments. Overall it is well-written and an interesting document of the work presented at the conference. It can be published as is, though one typo was noted as shown in the requested changes section of the report. This can be corrected at the proof stage
