Discrepancy in pd breakup reaction at Ep=13 MeV

We made three kinds of measurements at E p = 13  MeV ; i) D ( p , p p ) n experiment at pp FSI, ii) D ( p , p ) p n experiment at θ p = 10 ° – 60 ° , and iii) D ( p , p p ) 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.
