Calculations of quasielastic electron scattering from nuclei at high momentum transfers


Allder, Anne (1992) Calculations of quasielastic electron scattering from nuclei at high momentum transfers. Dissertation (Ph.D.), California Institute of Technology. doi:10.7907/d08g-aa33.


I perform calculations of high momentum-transfer, quasielastic electron scattering from nuclei using a relativistic, microscopic model of the reaction that includes the effects of final-state interactions via an eikonal approximation and the effects of color transparency via a cross-section that varies along the exit path of the proton. The results of this microscopic calculation agree to 5% with a semiclassical estimate based on the mean free path of the proton in the nuclear medium. The overall uncertainty in the calculation is on the order of 10%; this figure is dominated by uncertainties in the potential that describes the final state interaction. Color transparency effects an enhancement on the order of a few percent (in total cross-section) for Q^2=1 GeV^2, and ten percent for Q^2=10 GeV^2. The predictions of various specific transparency models differ by approximately 20%, and thus are probably not experimentally distinguishable for Q^2<10 GeV^2.
