Inclusive Scattering and Dynamics in Light Nuclei

PDF Version Also Available for Download.

Description

Inclusive scattering offers a unique opportunity to study nuclear dynamics in the regime of moderate momentum and energy transfers. We show that realistic models of nuclear interactions and current operators provide a quantitive description of the Alpha particle longitudinal and transverse responses measured in electron scattering. A consistend picture of in-medium nucleon dynamics naturally emerges from an analysis of these (e, e') data and quasi-elastic data from hadronic reactions on heavier nuclei. Its essential features are : (1) a significant quenching of the longitudinal strength; (2) a substantial enhancement of the transverse strength due to the two-nucleon currents required by ... continued below

Description

Inclusive scattering offers a unique opportunity to study nuclear dynamics in the regime of moderate momentum and energy transfers. We show that realistic models of nuclear interactions and current operators provide a quantitive description of the Alpha particle longitudinal and transverse responses measured in electron scattering. A consistend picture of in-medium nucleon dynamics naturally emerges from an analysis of these (e, e') data and quasi-elastic data from hadronic reactions on heavier nuclei. Its essential features are : (1) a significant quenching of the longitudinal strength; (2) a substantial enhancement of the transverse strength due to the two-nucleon currents required by gauge invariance; and (3) a large shift to higher energies of the isovector strength as observed in the charge-exchange response to hadronic probes. Within this theoretical framework the interactions and currents due to pion exchange play an absolutely crucial role.
