Measurements of inclusive pd breakup cross sections at low and intermediate energies

Inclusive experiments for D(p,p)pn breakup were performed at incident proton energies of 247 MeV and 13 MeV. At 247 MeV, the cross sections and analyzing power Ay measured at angles from 7 ° to 20 ° largely disagree with calculations even if a 2π‐exchange three‐nucleon force (2π3NF) effects are included, and the disagreement increases at forward angles. At 13 MeV, cross section measured at angles from 10 ° to 70 ° agrees well with pd calculation and 2π3NF effects are small. The large disagreement in pd breakup at 247 MeV may have some relationship with disagreements in pd scattering at 250 MeV.
