Abstract
The local density approximation (LDA) to exchange and correlation effe cts has well-known limitations. The nonlocal weighted density approxim ation (WDA) corrects some of those defects. This is illustrated here b y applications to free atoms and small atomic clusters. The WDA also i nduces a nonlocal kinetic energy functional that is tested for atoms. (C) 1995 John Wiley & Sons, Inc.
