Spectroscopy Symposium The 11th Annual Southeastern Sym posium on Spectroscopy, sponsored by the University of Florida and the Southeastern Association of Spectrographers will be presented at the Uni versity of Florida, Gainesville Fla., from January 21 to 24. Registration costs $20 which includes the annual banquet. Applications of Masers to Optical Emission Spectroscopy will be the major theme this year. Dr. T. A. Welton, Senior Scientist in the Physics Division at Oak Ridge National Lab oratory will present three lectures deal ing with the theory of lasers and masers with particular reference to spectroscopy. Frederick Brech, vice president and director of research for Jarrell-Ash will present three lectures on the applications of lasers to spec troscopy. Dr. V. A. Fassel, Iowa State University will present lectures con cerned with the effect of environment on the spectroscopic properties of flames and electrical discharges. Dr. Marvin Margoshes of the National Bureau of Standards will give three lectures on the following topics: De termination and Application of Atomic Transition Probabilities; Factors Af fecting Precision and Accuracy in the Spectroscopic Analysis of Solutions; and Design of Plasma Jet and GasStabilized Arc Sources. Further information on this sym posium may be obtained by writing to W. T. Tiffin, Metallurgical Research Laboratory, University of Florida, Gainesville, Fla.
Radioactive Isotope Applications A special conference, "Oak Ridge Radioisotope Conference-Applications to Physical Science and Engineering," will meet April 1 to 3, 1963, in Gatlinburg, Tenn. The conference is spon sored by the Oak Ridge Institute of Nuclear Studies, ORNL, and the Iso topes and Radiation Division of the American Nuclear Society, in coopera tion with the U. S. Atomic Energy Commission. Conference plans call for general papers to be presented on the first day, with special sessions de\'oted to physi cal science research and engineering ap plications on the following two days. The physics and chemistry sessions will include analytical procedures, exchange reactions, reaction rates, molecular structure, diffusion processes, colloid
and surface studies, catalysis, and re lated topics. More information is available from Oak Ridge Institute of Nuclear Studies, P. 0. Box 117, Oak Ridge, Tenn.

Single-Beam Readout Accessory permits Model 202 to operate in the single beam mode for in vestigating sources, for flame photometry or for absolute calibration w i t h external sources. The versatility and adjustability of the unit enable it to meet a broad range of experimental conditions. Time Drive Accessory, designed to record absorbance vs time ίη the Model 202, can be used to follow the kinetics of a chemical reaction at any predetermined wavelength in the normal range of the
