During our studies of the pd → n(pp) reaction at ANKE with neutron emission in backward direction, we have measured two protons at low relative momentum presumably in the 1S0 final state. Consecutively, this technique has been exploited together with the possibilities offered by the acceleration of polarised deuterons at COSY, to measure the d→p → (pp)1S0n charge–exchange reaction near the forward direction, i.e. where the four–momentum transfer t between the proton and neutron is small. our amplitude. Preliminary results of the first measurement of the charge–exchange deuteron breakup reaction at Td = 1.2 GeV will be presented. Results of a recent COSY beam polarimetry run will also be discussed.
