Discrepancy in pd breakup reaction at Ep=13 MeV

We made three kinds of measurements at Ep=13 MeV; i) D(p,pp)n experiment at ppFSI, ii) D(p,p)pn experiment at θp=10°–60°, and iii) D(p,pp)n experiment at many angle pairs around the space star. For an easy estimate of Coulomb effects in pd breakup reaction, we proposed Watson- Migdal & Faddeev calculation which was found to give nearly the same results as the pd calculation by Deltuva et al.. Cross sections of i) and ii) are well reproduced by the pd calculation, however, 10-15% discrepancy has been found between the cross section of iii) and the calculation.
