Resumen:
The longitudinal and transverse nuclear responses
to inclusive electron scattering reactions are
analyzed within the Random Phase Approximation (RPA) framework.
Several residual interactions are considered
and it is shown that the exchange terms in the RPA
make very difficult to find an effective residual
interaction capable of reproducing simultaneously the quasielastic
peak of both the longitudinal and transverse responses.
By means of a simplified model it is illustrated that the
residual interaction used in a ring approximation
must fulfill some restrictions in order to qualitatively
reproduce the full RPA results.
