We measured the cross section and response functions for the quasielastic O-16(e, e 'p) reaction for missing energies 25 less than or equal to E-m less than or equal to 120 MeV at missing momenta P-m less than or equal to 340 MeV/c. For 25 < E-m < 50 MeV and P-m approximate to 60 MeV/c, the reaction is dominated by a single ls(1/2) proton knockout. At larger P-m, the single-particle aspects are increasingly masked by more complicated processes. Calculations which include pion exchange currents, isobar currents, and short-range correlations account for the shape and the transversity, but for only half of the magnitude of the measured cross section.

Abstract
We measured the cross section and response functions for the quasielastic O-16(e, e 'p) reaction for missing energies 25 less than or equal to E-m less than or equal to 120 MeV at missing momenta P-m less than or equal to 340 MeV/c. For 25 < E-m < 50 MeV and P-m approximate to 60 MeV/c, the reaction is dominated by a single ls(1/2) proton knockout. At larger P-m, the single-particle aspects are increasingly masked by more complicated processes. Calculations which include pion exchange currents, isobar currents, and short-range correlations account for the shape and the transversity, but for only half of the magnitude of the measured cross section.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
