Different effective interactions based on a standard model of the type g'+V_pi+V_rho are employed. For each momentum transfer, we have obtained the value of g'_0 permitting the ring response to match the position of the peak and/or the non-energy weighted sum rule provided by the random-phase approach has been obtained. It is found that, in general, it is not possible to reproduce both magnitudes simultaneously for a given g'_0 value.", "revisions": [ { "version": "v1", "updated": "1999-02-11T18:00:16.000Z" } ], "analyses": { "keywords": [ "quasielastic electron scattering", "nuclear transverse response", "non-energy weighted sum rule", "random-phase approach", "ring approximation calculations" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Phys.
