Abstract
The longitudinal (e,e'); response function of He-4 is calculated precisely with full final state interaction. The explicit calculation of the four-body continuum States is avoided by the method of integral transforms. Precision tests of the response show the high level of accuracy. Nonrelativistic nuclear dynamics are used. The agreement with experimental data is very good over a large energy range for all considered momentum transfers (q = 300, 400, 500 MeV/c). Only at higher q the theoretical response overestimates the experimental one beyond the quasielastic peak.File in questo prodotto:
