Scattering of GeV electrons by light nuclei

The cross section for inclusive scattering of high-energy electrons by ${}_{}{}^2{}_{}{}^{}\mathrm{H}$, ${}_{}{}^3{}_{}{}^{}\mathrm{He}$, and ${}_{}{}^4{}_{}{}^{}\mathrm{He}$ with momentum transfer ‖q‖∼2 GeV/c is calculated using realistic spectral functions. The final-state interaction effects are treated with the correlated Glauber approximation, and the possible occurrence of color transparency is considered. The results are in fair agreement with the SLAC data and confirm the presence of high-momentum components in the deuteron wave function. The final-state interaction effects are significant in ${}_{}{}^3{}_{}{}^{}\mathrm{He}$ and ${}_{}{}^4{}_{}{}^{}\mathrm{He}$, and there seem to be systematic differences between theory and experiment at large ω in ${}_{}{}^4{}_{}{}^{}\mathrm{He}$.
