Abstract

The reaction ³He(e, e′d)p was measured at four-momentum transfer q = 420 MeV, for proton recoil momentum P_r = 22, 54, and 62 MeV/c, in parallel deuteron kinematics. Longitudinal (L) and transverse (T) response functions were obtained by means of Rosenbluth separations. The separated response functions are, respectively, found to be dominated by the contributions of isoscalar and isovector two-body currents. The L/T ratios are about 3.5. This is an order of magnitude lower than that for elastic scattering on a free deuteron, or what would be expected for a purely isoscalar transition, but approximately agrees with what is theoretically expected for isoscalar plus isovector contributions.
