Electrodisintegration of 3He

The continuum spectra of ³He have been measured up to excitation energies of 40 MeV by means of inelastic electron scattering. Incident electron beam energies between 60 and 120 MeV were used, corresponding to a momentum transfer range of 0.3 fm^-1 to 1.1 fm^-1. Scattered electrons were observed at two angles, 92.6° and 127.7°. The radiation corrected spectra and the form factors are presented, and compared with calculations based on a zero-range approximation. In this model, the sharp rise from the p+d threshold previously reported may be identified as a ²S-->²S Coulomb monopole transition.
