Abstract
In this contribution, vector analyzing powers are presented for the proton-deuteron break-up reaction studied using a polarised-proton beam at 135 MeV. For the experiment, we used the Big Instrument for Nuclear-polarisation Analysis (BINA) at KVI, the Netherlands. With this setup, we determined, for the first time, \(A_x\) for a large range in the kinematical S, polar and azimuthal angles of the two outgoing protons. Our data are reasonably well described by Faddeev calculations for kinematical configurations at which the three-nucleon force effect is predicted to be small. However, striking discrepancies are observed at specific configurations, for which the relative azimuthal angle between the two protons becomes small. In this contribution, some of these configurations along with the analysis techniques are presented.
