Discrepancy of Cross Sections in pd Breakup Reactions at Ep = 250 MeV

In our previous inclusive experiment on 2H(p, p)pn at 247 MeV, the measured cross section at forward angles is about twice larger than 3N calculation with ππ 3NF. Therefore, we have made an exclusive experiment on 2H(p, p 1 p 2)n at the same energy. The preliminary data suggest that the cross section was enhanced at forward angle of θ 1 and θ 2.
