The D(e,e'p)n reaction cross section has been measured for recoil mome
nta ranging from 17 MeV/c up to 950 MeV/c at momentum transfers betwee
n 600 MeV/c and 700 MeV/c. At recoil momenta above 400 MeV/c, the gros
s features of the cross section are only reproduced if virtual nucleon
excitations are included in the calculations. (C) 1998 Published by E
