Anomalies in Quasifree Scattering fromp+He3Reactions

Abstract

The reactions ${\mathrm{He}}^3\mathrm{}(p,pd)p$ and ${\mathrm{He}}^3\mathrm{}(p,2p)d$ have been studied at 35 MeV. A dominant feature of these data is $p-p$ and $p-d$ quasielectric scattering. A plane-wave impulse approximation gives a qualitative fit to the ${\mathrm{He}}^3\mathrm{}(p,2p)d$ data, but fails to explain the ${\mathrm{He}}^3\mathrm{}(p,pd)p$ data. Various possible explanations are discussed.
