Abstract

Elastic and inelastic cross sections for 180° electron scattering from He3 were measured at incident electron energies of 40.44, 50.58, and 60.63 MeV. Our radiatively corrected cross section measurements are in good agreement with theoretical calculations of the behavior near the two-body breakup threshold at 5.5 MeV. The measurements were also compared to cross sections calculated in the zero-range approximation and to sum rules. At q=0.602 fm1 the measured magnetic radius was r=1.79±0.14 fm. The possibility of the existence of a state at about 10 MeV excitation is also discussed.

NUCLEAR REACTIONS He3(e,e); θ=180°, E0=40, 51, 61 MeV; measured σ for Ex=0 to E02. Deduced magnetic radius.
