Abstract

Cross sections were measured for the near-threshold electrodisintegration of 3He at momentum transfer values of q = 2.4, 4.4, and 4.7 fm -1. From these and prior measurements the transverse and longitudinal response functions RT and RL were deduced. Comparisons are made against previously published and new nonrelativistic A = 3 calculations using the best available nucleon-nucleon NN potentials. In general, for q <2 fm-1 these calculations accurately predict the threshold electrodisintegration of 3He. Agreement at increasing q demands consideration of two-body terms, but discrepancies still appear at the highest momentum transfers probed, perhaps due to the neglect of relativistic dynamics, or to the underestimation of high-momentum wave-function components.
