{"doi":"10.1103/physreva.38.3098","title":"Density-functional exchange-energy approximation with correct asymptotic behavior","abstract":"Current gradient-corrected density-functional approximations for the exchange energies of atomic and molecular systems fail to reproduce the correct 1/r asymptotic behavior of the exchange-energy density. Here we report a gradient-corrected exchange-energy functional with the proper asymptotic limit. Our functional, containing only one parameter, fits the exact Hartree-Fock exchange energies of a wide variety of atomic systems with remarkable accuracy, surpassing the performance of previous functionals containing two parameters or more.","journal":"Physical Review A","year":1988,"id":9570,"datarank":23.212536648486143,"base_score":10.882490138206446,"endowment":10.882490138206446,"self_citation_contribution":1.632373520730967,"citation_network_contribution":21.580163127755178,"self_endowment_contribution":1.632373520730967,"citer_contribution":21.580163127755178,"corpus_percentile":99.5,"corpus_rank":51,"citation_count":53235,"citer_count":189,"citers_with_citation_signal":189,"citers_with_endowment":189,"datacite_reuse_total":0,"is_dataset":false,"is_oa":false,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"1988-09-01","authors":[{"id":50003,"name":"Axel D.
