Abstract

The five-fold differential cross section for the 12C(e ep , ) ′ 11B reaction was determined over a missing momentum range of 200–400 M − eV c 1 , in a kinematics regime with xB > 1 and Q = 2.0 2 − (GeV c )1 2. A comparison of the results with previous lower missing momentum data and with theoretical models are presented. The extracted distorted momentum distribution is shown to be consistent with previous data and extends the range of available data up to 400 M − eV c 1 . The theoretical calculations are from two very different approaches, one mean field and the other short range correlated; yet for this system the two approaches show striking agreement with the data and each other up to a missing momentum value of 325 M − eV c 1 . For larger momenta, the calculations diverge which is likely due to the factorization approximation used in the short range approach.
