Cross section enhancement in \mbox{\boldmath $pd$} breakup at \mbox{\boldmath $E_p=$} 250 MeV

ORAL

Abstract

Up to a few times enhancement of $pd$ breakup cross section was found in our inclusive experiment of $^2$H$(p,p_1)pn$ at $E_p=$ 250 MeV. The enhancement around $E_{p_1}=$ 150 MeV has been investigated in our exclusive experiment $^2$H$(p,p_1p_2)n$ at the same incident energy in the range of $\theta _2= 35^{\circ}-80^{\circ}$. We found that the exclusive cross section enhancement depend on $\theta _2$. Enhancement of $pd$ elastic scattering cross section has been found also at the incident energy.
