摘要

The E12-14-012 experiment, performed in Jefferson Lab Hall A, has measured the (e,e′p) cross section in parallel kinematics using a natural titanium target. In this paper, we report the analysis of the dataset obtained in different kinematics for our solid natural titanium target. Data were obtained in a range of missing momentum and missing energy between 15≲pm≲250 MeV/c and 12≲Em≲80 MeV, respectively, and using an electron beam energy of 2.2 GeV. We measured the reduced cross section with ∼7% accuracy as a function of both missing momentum and missing energy. Our Monte Carlo simulation, including both a model spectral function and the effects of final-state interactions, satisfactorily reproduces the data.Received 27 September 2022Accepted 6 January 2023DOI:https://doi.org/10.1103/PhysRevD.107.012005© 2023 American Physical SocietyPhysics Subject Headings (PhySH)Research AreasNeutrino interactionsNuclear reactionsParticle interactionsNuclear PhysicsParticles & Fields
