"Theoretical Aspects of Laser Ra diation and Its Interaction with Atomic and Molecular Systems" has just been published by the Univer sity of Rochester with funds from the National Science Foundation (NSF). Drafted by 40 participants at a univer sity workshop sponsored by NSF June 3-5,1977, this 148-page report focuses on the assessment of current theory, how it relates to practical laser situa tions and experiments, and a projec tion of future developments. Three general areas are covered: spectrosco py, collision dynamics, and laser oper ation. Copies are available from the NSF's Division of Chemistry, 1800 G St., N.W., Washington, D.C. 20550. The Dosimeter Corp. of America (DCA) now manufactures all prod ucts formerly manufactured by EON Corp., which discontinued oper ation in December 1977. All orders for radiation and/or safety related prod ucts, including Geiger Muller tubes, should be sent to DCA corporate of fices in Cincinnati: 6106 Interstate Circle, Cincinnati, Ohio 45242 (513793-6051). Prompted by the enormous growth in applications of thermal analysis, par ticularly in the area of plastics and quality control, Perkin-Elmer will host 15 seminars in thermal analy sis across the country. Discussions will include applications of the Model DSC-2 differential scanning calorime ter, TGA thermogravimetric analyzer, and the TMA thermomechanical ana lyzer. The new System 4 microproces sor controller for thermal analysis will also be demonstrated. Anyone inter ested should contact a Perkin-Elmer representative in the appropriate re gion.
