Measurement of 2H(p, pp) n cross sections at Ep = 250 MeV

In our previous inclusive experiment on pd breakup at E p = 247 MeV, we found experimental cross section is about twice larger than 3N calculation with ππ 3NF at forward angle. Therefore we made exclusive measurement of 2 H (p, p1 p2)n cross section at the same 247 MeV. Preliminary data indicate that the cross section enhancement appears at forward angles of θ 1 and θ 2. We made also inclusive experiment again and confirmed the previous data.
