Absolute differential cross sections for the threshold electrodisintegration of the deuteron with good resolution were measured at a laboratory scattering angle of 160{degree} for five values of Q{sup 2} ranging from 8.66 to 42.4fm{sup {minus}2}. Comparisons of the data averaged over E{sub np} from 0 to 3 MeV and from 0 to10 MeV are made with nonrelativistic meson exchange calculations. These calculations are sensitive to the nucleon electromagnetic form factors, nucleon-nucleon potential, and relativistic effects. The data are also compared with a hybrid quark-hadron model calculation that describes the deuteron as a six-quark cluster for the short range part of the interaction. Some of these calculations can describe the data reasonably well over certain ranges of Q{sup 2}; however, none of these calculations can accurately describe the data over the entire measured Q{sup 2} range. {copyright} {ital 1997} {ital The American Physical Society}
