Title: Measurement of the 12C(e,e'p)11B Two-Body Breakup Reaction at High Missing Momentum Values

Abstract

The five-fold differential cross section for the 12C(e,e'p)11B reaction was determined over a missing momentum range of 200-400 MeV/c, in a kinematics regime with Bjorken x > 1 and Q2 = 2.0 (GeV/c)2. A comparison of the results and theoretical models and previous lower missing momentum data is shown. The theoretical calculations agree well with the data up to a missing momentum value of 325 MeV/c and then diverge for larger missing momenta. The extracted distorted momentum distribution is shown to be consistent with previous data and extends the range of available data up to 400 MeV/c.

  • A particular three-body mechanism is responsible for the missing strength which has been reported in {sup 3}He(e,e{prime}p) reactions at missing momentum above 700 MeV/c. It corresponds to the absorption of the virtual photon by a nucleon at rest which subsequently propagates on-shell and emits a meson which is reabsorbed by the pair formed by the two other nucleons. Its amplitude, which is negligible in photon induced reactions as well as in the electro-production of an on-shell meson, becomes maximal in the quasi-free kinematics (X=1). It relates the amplitude of the {sup 3}He(e,e{prime}p)D reaction to the amplitude of pD elastic scatteringmore » at backward angles.« less
  • The cross section of the {sup 4}He(e,e'p){sup 3}H reaction has been measured for missing momenta 220 {le}p{sub m}{le}690 MeV/c to study high-momentum components of the nuclear wave function and the reaction mechanism for this transition. The zero predicted in the plane-wave impulse approximation (PWIA) cross section, due to the underlying pt momentum distribution, is found to be washed out. Three types of calculations indicate that this is caused by final-state interactions and contributions from two-body currents. The calculations reproduce the high p{sub m} (600-690 MeV/c) data, although due to different ingredients in the models.
  • Results of the Jefferson Lab Hall A quasielastic 3He(e,e'p)pn measurements are presented. These measurements were performed at fixed transferred momentum and energy, q = 1502 MeV/c and omega = 840 MeV, respectively, for missing momenta {+-} up to 1 GeV/c and missing energies in the continuum region, up to pion threshold; this kinematic coverage is much more extensive than that of any previous experiment. The cross section data are presented along with the effective momentum density distribution and compared to theoretical models.
  • We measured the cross section and response functions for the quasielastic {sup 16}O( e,e'p) reaction for missing energies 25{<=}E{sub m}{<=}120 MeV at missing momenta P{sub m}{<=}340 MeV/c . For 25<E{sub m}<50 MeV and P{sub m}{approx}60 MeV/c , the reaction is dominated by a single 1s{sub 1/2} proton knockout. At larger P{sub m} , the single-particle aspects are increasingly masked by more complicated processes. Calculations which include pion exchange currents, isobar currents, and short-range correlations account for the shape and the transversity, but for only half of the magnitude of the measured cross section.
  • The cross section of the 4He(e,e'p)3H reaction has been measured for missing momenta 220<= pm <= 690 MeV/c to study high-momentum components of the nuclear wave function and the reaction mechanism for this transition. The zero predicted in the plane-wave impulse approximation (PWIA) cross section, due to the underlying pt momentum distribution, is found to be washed out. Three types of calculations indicate that this is caused by final-state interactions and contributions from two-body currents. The calculations reproduce the high pm (600-690 MeV/c) data, although due to different ingredients in the models.
