Dr. Delana Nivens, Dr. Cliff Padgett, and Dr. William Baird and undergraduate chemistry majors Chaney Durham and Jeff Chase have published a paper in the Journal of Chemical Education.  The paper, published in the March 10, 2011 issue of the Journal is titled "Chemical Environment Effects on Kβ/Kα Intensity Ratio: An X-ray Fluorescence Experiment on Periodic Trends"and found on pages 819-821.  The paper describes a laboratory for physical chemistry lab that investigates chlorine Kα and Kβ peaks in several group 1 salts. The ratio of the peak intensity is sensitive to the local chemical environment of the chlorine atoms studied in this experiment and it shows a periodic trend for these salts.
