QUASI-ELASTIC AND INELASTIC INCLUSIVE ELECTRON-SCATTERING FROM AN OXYGEN JET TARGET

The results of an experiment on inclusive electron scattering from an oxygen jet target, performed in a wide range of energy and momentum tr ansfer covering both quasi-elastic and Delta(1232) resonance regions, are reported. In the former region the theoretical predictions, obtain ed including effects of nucleon-nucleon correlations in both initial a nd final states, give a good description of the experimental data. In the inelastic region a broadening as well as a damping of the resonant part of the cross section with respect to the free nucleon case is ob served. The need of more detailed calculations including nuclear struc ture effects on the electroproduction cross section of nucleon resonan ces is highlighted.
