4. . ,. • ' . ■fbfc s DR. JOHN S. TOLL (right) with President Wilson H. Elkins announces the decision of the Atomic Energy Commission to grant $3 million to the construction of a Progress: Physical Science 100 million electron volt cyclotron at the University in College Park. The project was begun this year and com- pletion is expected in three years. Physics NUMEROUS ADVANCES in development and program enlargement were made by the physics department this year. Shown on the frontispiece of the TERRAPIN is a bubble cham- ber photograph in which a new mode of decay of a rare subatomic particle, omega minus, was observed. The event was produced at the Brookhaven National Laboratory by a team of physicists from the University and the Naval Research Laboratory. The decay mode was predicted by present theoretical ideas before its demonstration experimentally. Also this year, the Atomic Energy Commis- sion have agreed to negotiate a contract for design and construction of a cyclotron. The AEC will provide $3 million toward the c(»st of the facility. The machine ' s design will permit ac- celeration of deuterons (heavy hydrogen nuclei) and other heavy nuclei, as well as protons. The equipment is expected to achieve a proton energy of about 100 million electron volts. THE THREE MILLION electron volt Van de Graaff generator is used to accelerate positively charged ions into various light nuclei to study their properties.

During Dean Eppley ' s student career, he distinguished himself in athletics, particularly football and track. In 1924, he returned to his true love, athletics, as track coach. In 1935, his team won the sprint medley relay, and in 1940, the two mile, four mile, and distance medley re- lay. Both of these years, the wins were the Championships of America at Penn Relays. One of the students coached by Eppley, present track coach Jim Kehoe, who has known the Dean for close to 30 years said, He is a very sincere, conscientious gentleman and he has given excellent guidance and assistance to hundreds of people at the University. In 1935, he became Director of Ath- letics and, in later years, became Presi- dent of the Southern Conference and the Atlant ic Coast Conference. He became the first Dean of Men in 1936, a position which he held until his retirement last year. Dean Eppley continued his affilia- tion with the Army reserve from 1919 until 1950. In World War II he was caUed for active duty and served as a colonel in Headquarters, Army Ground Forces. He received the Legion of Honor for his service. ■RP B tl If • 1 1 -■ -so 1 ' B 1 1 jjjQ j HHH|H| i 1 - AS A CAVALRY officer in World War I, Eppley (right) appears with a French interpreter and a lieutenant from the 2nd Cavedry. AS A COLONEL, Dean Eppley was awarded the Legion of Merit for his service in World War II. Dean Eppley is married to the former Eliza- beth Flenner and has two daughters, a son, and eight grandchildren. His wife and two daughters are all alumnae of the University of Maryland. His membership in societies includes Sigma Chi, Phi Kappa Phi, Omicron Delta Kappa, Alpha Phi Omega, Phi Eta Sigma, Pi Delta Epsilon, Scabbard and Blade, Pershing Rifles, and Student Grange. Within the records of this University let it be said that here was a man, who with the trowel of service and the mortar of dedication, helped build this monument of education.

Chemistry THE CHEMISTRY department is presently engaged in numerous research programs in- cluding an examination of properties of sub- stances under very high pressure by Raman and infrared spectroscopy, the kinetics of competi- tive and consecutive reactions, chemical phenomena caused by ultrasonics, and the elec- tro-conductivity of complex salts. In addition, work is being done of the determination of molecular structures. Kinetic and reaction rate studies which utiHze mass spectroscopy and nuclear magnetic resonance techniques are also under research in the department. In the area of organic chemistry, methods are being studied in the synthesis of monomers important in the preparation of polymers, highly unsaturated compounds, substances of plant hormonal activity, complex heterocyclics and polyphenyls. Biochemistry investigations include kinetics of enzyme catalyzed reactions, and the role of trace metal in biological systems.
