✦ Synopsis
Scalar, baryon and vector-current densities in coordinate and momentum space are calculated within a relativistic mean-field model. The role of the low components of the bound nucleon wave function is investigated in detail for different spin-orbit partner shells. We show that the relative importance of the negative-energy projection components can be explained from the different quantum numbers involved in the relativistic wave function. This fact has proved to be important in the analysis of various electron scattering observables even for low-medium values of the bound nucleon momentum. (~ 1998 Elsevier Science B.V.
