Abstract

Proton-deuteron breakup coincidence data obtained with the BOL system and covering a large fraction of phase space at Ed = 26.5 MeV (Ep = 13.25 MeV) are compared with Faddeev calculations using the Malfliet-Tjon (MT) I–III and I–IV S-wave nucleon-nucleon potentials. Data and calculations are represented in terms of two-dimensional histogram plots. Correlations are discussed between different plots, showing the relative difference in cross section between the MT I–III and the MT I–IV potential (the so-called sensitivity), the theoretical cross section itself and the discrepancy between theory and experiment. The theoretical and experimental data near the main discrepancy region are studied in terms of recoil centre of mass coordinates. An approximately rotationally symmetric pattern aligned with the beam direction is observed for the discrepancy between theory (MT I–III) and experiment, and for the sensitivity (MT I–III, MT I–IV). New measurements that might be particularly suitable to test existing theoretical models as well as further theoretical analyses of our data are suggested.
