摘要：

The local density approximation (LDA) for the exchange potential of QHD-I presented in a previous publication [R. N. Schmid, E. Engel, and R. M. Dreizler, Phys. Rev. C 52, 164 (1995)] is extended to rho mesons and pions to allow for realistic applications of the density functional approach to quantum hadrodynamics. Some results for spherical nuclei show that the LDA is an accurate approximation to the nonlocal Hartree-Fock-exchange potential also on the level of QHD-II.
