d(e,e'p) Studies of Exclusive Deuteron Electro-Disintegration

Abstract

The d(e,e'p) cross section was measured at momentum transfers $Q^2=$ 0.8, 2.1 and 3.5 $(GeV/c{)}^2$ covering a wide range of proton kinematics at each $Q^2$ setting that made it possible to study this reaction as a function of missing momentum as well as a function of the neutron laboratory recoil angle $\hat{I}{¸}_{nq}$. Missing momentum distributions were determined for fixed values of $\hat{I}{¸}_{nq}$ up to missing momenta of 0.65 $GeV/c$. For the two larger momentum transfer settings, the characteristics of the experimental momentum distributions confirm the theoretical prediction that final state interactions (FSI) contribute maximally around a $\hat{I}{¸}_{nq}\sim 70^{\circ }$, while for $\hat{I}{¸}_{nq}<45^{\circ }$ FSI are significantly reduced. The data at reduced FSI settings were best reproduced by calculations using the CD-Bonn potential wave functions.
