{"doi":"10.1107/s0567739468000707","title":"A semi-empirical method of absorption correction","abstract":"An extension of Furnas's method is described. The variation of intensity of an axial reflection as the crystal is rotated about the goniometer axis is used to give a curve of relative transmission T against azimuthal angle ϕ for the corresponding reciprocal lattice level. Transmission coefficients for any general reflexion hkl are then given approximately by T(hkl) = [T(ϕinc) + T(ϕret)]/2 where ϕinc and ϕret are the azimuthal angles of the incident and reflected beams. Equations are derived for (ϕinc and ϕret and the accuracy of the method is discussed.","journal":"Acta Crystallographica Section A","year":1968,"id":1933,"datarank":30.69358410510229,"base_score":8.919586920999915,"endowment":8.919586920999915,"self_citation_contribution":1.3379380381499875,"citation_network_contribution":29.355646066952303,"self_endowment_contribution":1.3379380381499875,"citer_contribution":29.355646066952303,"corpus_percentile":98.1,"corpus_rank":2154,"citation_count":7476,"citer_count":198,"citers_with_citation_signal":198,"citers_with_endowment":198,"datacite_reuse_total":0,"is_dataset":false,"is_oa":false,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"1968-05-01","authors":[{"id":22071,"name":"D.
