Abstract
The continuum spectra of $^{3}\mathrm{He}$ 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 ${\mathrm{fm}}^{\ensuremath{-}1}$ to 1.1 ${\mathrm{fm}}^{\ensuremath{-}1}$. Scattered electrons were observed at two angles, 92.6\ifmmode^\circ\else\textdegree\fi{} and 127.7\ifmmode^\circ\else\textdegree\fi{}. 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 $^{2}S\ensuremath{\rightarrow}^{2}S$ Coulomb monopole transition.NUCLEAR REACTIONS $^{3}\mathrm{He}(e, {e}^{\ensuremath{'}})$, ${E}_{x}=0\ensuremath{-}40$ MeV; measured $\ensuremath{\sigma}(E; \ensuremath{\theta})$; $\ensuremath{\theta}=92.6\ifmmode^\circ\else\textdegree\fi{} \mathrm{and} 127.7\ifmmode^\circ\else\textdegree\fi{}$.
