Chemical Effects on the K_{β}/K_{α} X-ray Intensity Ratios for Some First-row Transition Element Compounds Were Studied Experimentally and Calculated. the Vacancies in the K Shell Were Created by 59.5 keV γ rays from an ^{241}Am Radioactive Source and Characteristic X-ray Radiation from Sample Was Measured by Using Si(li) and Ge(li) Detectors. the Calculations Were Carried Out Using Brunner's Model. the Calculated Relative K_{β}/K_{α} X-ray Intensity Ratios Are in Good Agreement with the Present and the Previously Published Experimental Data.
