Narrow structure in the analyzing power of the 3He(p↘,d)X reaction at 0.8 GeV

The analyzing power Ay has been measured for the 3He(p↘,d)X reaction at a deuteron angle of 22° (lab.) and a proton energy of 0.8 GeV. Narrow resonances in the missing mass dependence of Ay were observed. The resonance energies appear to agree with previous cross section data and with energies predicted by theoretical models.
