The coincidence cross section and the interference structure function, R{sub LT}, were measured for the {sup 12}C(e,e{sup {prime}}p)thinsp{sup 11}B reaction at quasielastic kinematics and central momentum transfer of {vert_bar}{rvec q}{vert_bar}=400thinspMeV/c. The measurement was at an opening angle of {theta}{sub pq}=11{degree}, covering a range in missing energy of E{sub m}=0 to 65 MeV. The R{sub LT} structure function is found to be consistent with zero for E{sub m}{gt}50thinspMeV, confirming an earlier study which indicated that R{sub L} vanishes in this region. The integrated strengths of the p- and s-shell are compared with a distorted wave impulse approximation (DWIA) calculation. The s-shell strength and shape are also compared with a Hartree Fock{endash}random phase approximation (HF-RPA) calculation. The DWIA calculation does not succeed in giving a consistent description of both the cross section data and the extracted R{sub LT} response for either shell. The HF-RPA calculation describes the data more consistently, which may be due to the inclusion of 2-body currents in this calculation. {copyright} {ital 1998} {ital The American Physical Society}
