نویسنده
چکیده
A relativistic finite nucleus calculation using a Dirac optical potential is used to investigate the importance of final state interactions [FSI] at large momentum transfers in inclusive quasielastic electronuclear reactions. The optical potential is derived from first-order multiple scattering theory and then is used to calculate the FSI in a nonspectral Green's function doorway approach. At intermediate momentum transfers excellent predictions of the quasielastic 56 Fe(e, e ′) experimental data for the longitudinal response function are obtained. In comparisons with recent measurements at | q| = 1.14 GeV/c the theoretical calculations of R L give good agreement for the quasielastic peak shape and amplitude, but place the position of the peak at an energy transfer of about 40 MeV higher than the data.

Color transparency is the vanishing of initial and final state interactions, predicted by QCD to occur in high momentum transfer quasielastic nuclear reactions. For specific reactions involving nucleons, the initial and final state interactions are expected to be dominated by exchanges of pions. We argue that these interactions are also suppressed in high momentum transfer nuclear quasielastic ...

An exactly solvable model is used to investigate the assumptions behind color transparency. 1 INTRODUCTION Color transparency (CT) is the anomalously high transparency of the nucleus to nucle-ons in quasi-elastic high-momentum transfer nuclear processes, measured with resolution good enough to insure that no " extra " pions are produced. This means that the ab-sorptive nuclear optical potential...

A many-body calculation of Li is presented where the only input is the welltested, finite-range D1S effective interaction of Gogny. Pairing correlations are included in a constrained Hartree-Fock-Bogolyubov calculation, while long-range collective correlations are introduced using a GCM derived calculation. Correlations are found to play an important role in describing Li. A substantive underly...
