LOCAL EXCHANGE-CORRELATION FUNCTIONAL - NUMERICAL TEST FOR ATOMS AND IONS - COMMENT

Zhao and Parr [Phys. Rev. A 46, R5320 (1992)] recently introduced an e xchange-correlation functional for the local-density approximation of the density-functional theory. In this paper we report results for ato ms, molecules, and crystalline solids using their functional as well a s traditional ones. We conclude that their functional yields a better description of neither the ionization energies nor of the chemical bon d in polyatomic systems.
