Measurement of²H(p, pp) ncross sections atE_p= 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 pi pi 3NF at forward angle. Therefore we made exclusive measurement of H-2(p, p(1)p(2))n cross section at the same 247 MeV. Preliminary data indicate that the cross section enhancement appears at forward angles of theta(1) and theta(2). We made also inclusive experiment again and confirmed the previous data.
