William H. Saunders

Professor Emeritus of Chemistry

Ph.D. 1952, Northwestern University

RESEARCH INTERESTS Physical-organic chemistry: ab initio and valence bond SCF calculations, proton transfer processes, mechanisms of elimination reactions, and kinetic isotope eects.

BILL SAUNDERS continues valence bond calculations on elimination reactions. Current computational studies are aimed at providing evidence for the prediction that truly synchronous E2 reactions are rare because they have high energy barriers. I at- tended the Reaction Mechanisms Conference at the University of North Carolina. Nonscientic activities included visits in June and August to the Stratford Shakespeare Festival in Canada, the latter trip along with daughter Anne and two granddaughters, Zoe and Sara. In July, Dave and Marty Wilson visited Rochester and stayed with me. Dave was a chemistry faculty member during

my early years at the University of Rochester. e bicycle trip of the year was to the Andalusia region of Spain in November. We saw many examples of Muslim inuence in Seville, Cordoba, and Granada. During the time that they were dominant they were more tolerant of other religions than were the Christians who followed them. Again at Christmas time there were visits from Anne, her two girls, Claude, his wife Gulchin, and stepdaugher Nina. My remaining travel was in early April to North Carolina, where the spring was much more advanced than in upstate New York.

Wolf-Udo Schröder

Professor of Chemistry

Ph.D. 1971, University of Darmstadt, Germany

RESEARCH INTERESTS Basic and applied nuclear science: dynamics of complex nuclear reactions at intermediate and high energies; dissipation, relaxation and other transport phenomena; non-equilibri- um eects; thermodynamics of nuclear disintegration and transmutation; the equation of state of nuclear matter. Beyond the mean eld: correlations and clusterization of nuclear matter. Chemi-and physisorption of tritium in metals.

UDO SCHRÖDER’s group continued research in radio-chem- istry, heavy-ion reaction dynamics, as well as technical R&D. In collaborative experiments with a group from the UR Labora- tory for Laser Energetics, interactions of tritriated compounds with metallic surfaces and metal lattices were studied. ese processes are of interest to the nuclear power industry. Results obtained from the group’s experiments with thermal and RF plasma desorption techniques were presented on several meet- ings by the involved students and in a peer-reviewed publica- tion.

Technical progress has also been made in the identication of heavy nuclear particles stopping in silicon detectors. A simple

and economical method has been devised to identify such par- ticles based on their time evolved ionization track.

Experimental and theoretical results on cluster emission in heavy-ion induced reactions have been presented by several group members at national and international conferences. e theoretical model developed by the group to describe the stabil- ity and ssion-like disintegration processes of highly unstable, hot nuclei has been extended further. It has been successful in predicting a host of previously puzzling observations in nuclear decay within a cohesive, plausible physical picture. Most re- cently, the model has been employed to explain the eects of a quantum symmetry leading to certain isotopic regularities
