Popis: We use the relativistic distorted wave impulse approximation to analyze data on ${}^{16}\mathrm{O}{(e,e}^{\ensuremath{'}}{p)}^{15}\mathrm{N}$ at $|{Q}^{2}|l~0.4 (\mathrm{GeV}{/c)}^{2}$ that were obtained by different groups and seemed controversial. Results for differential cross sections, response functions, and ${A}_{\mathrm{TL}}$ asymmetry are discussed and compared to different sets of experimental data for proton knockout from ${p}_{1/2}$ and ${p}_{3/2}$ shells in ${}^{16}\mathrm{O}.$ We compare with a nonrelativistic approach to better identify relativistic effects. The present relativistic approach is found to accommodate most of the discrepancy between data from different groups, smoothing a long standing controversy.
