Longitudinal and Transverse Quasi-Elastic Response Functions of Light Nuclei

PDF Version Also Available for Download.

Description

The {sup 3}He and {sup 4}He longitudinal and transverse response functions are determined from an analysis of the world data on quasi-elastic inclusive electron scattering. The corresponding Euclidean response functions are derived and compared to those calculated with Green's function Monte Carlo methods, using realistic interactions and currents. Large contributions associated with two-body currents are found, particularly in the {sup 4}He transverse response, in agreement with data. The contributions of two-body charge and current operators in the {sup 3}He, {sup 4}He, and {sup 6}Li response functions are also studied via sum-rule techniques. A semi-quantitative explanation for the observed systematics in ... continued below

Description

The {sup 3}He and {sup 4}He longitudinal and transverse response functions are determined from an analysis of the world data on quasi-elastic inclusive electron scattering. The corresponding Euclidean response functions are derived and compared to those calculated with Green's function Monte Carlo methods, using realistic interactions and currents. Large contributions associated with two-body currents are found, particularly in the {sup 4}He transverse response, in agreement with data. The contributions of two-body charge and current operators in the {sup 3}He, {sup 4}He, and {sup 6}Li response functions are also studied via sum-rule techniques. A semi-quantitative explanation for the observed systematics in the excess of transverse quasi-elastic strength, as function of mass number and momentum transfer, is provided. Finally, a number of model studies with simplified interactions, currents, and wave functions is carried out to elucidate the role played, in the full calculation, by tensor interactions and correlations.
