Quasifree Electron-Proton Scattering inH3andHe3

Measurements have been made of the cross sections of coincidences between scattered electrons and ejected protons, when targets of ${\mathrm{H}}^3$ and ${\mathrm{He}}^3$ are bombarded with 550-MeV electrons. The variation of the cross section with proton angle and proton energy has been studied for fixed electron angle and energy. The results are compared with theoretical calculations based on different three-body nuclear wave functions.
