Abstract
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 investiga ted in detail for different spin-orbit partner shells. We show that th e relative importance of the negative-energy projection components can be explained from the different quantum numbers involved in the relat ivistic wave function. This fact has proved to be important in the ana lysis of various electron scattering observables even for low-medium v alues of the bound nucleon momentum, (C) 1998 Elsevier Science B,V.
