The inelastic scattening of electrons from He/sup 4/ which corresponds to a disintegration of the nucleus was studied for incident electron energies of 400 and 500 Mev at laboratory angles from 45 to 135 deg . The energy spectra of the scattered electrons were measured, and absolute cross sections were found by comparison with elastic scattering from hydrogen. The curves were corrected for electron radiation. Within the validity of adapting to He/sup 4/ one of the results of the Goldberg theory of deuteron electrodisintegration, the cross sections at the maxima of the curves gave a value for M(l/p)/sub i of (7.5 plus or minus 1.5), where M is a nucleon mass and (l/p)/sub i is the expectation value of the reciprocal of the momentum of a nucleon bound in He/sup 4/. With a single exception, the energy-integrated cross sections d sigma /sub id OMEGA agreed within experimental error with d sigma /sub i/d OMEGA = 2(d sigma /sub p//d OMEGA + d sigma /sub n//d OMEGA ), where d sigma /sub p//d OMEGA is the free-proton cross section and d sigma /sub n//d OMEGA is the neutron cross section found from inelastic scattering from deuterium.
