Biographical Sketch

Prof. Cline received his B.Sc. in Physics, (1957) and his Ph.D. in Physics (1963) both from the University of Manchester. He joined the University of Rochester in 1963 as a Research Associate, and was promoted to Assistant Professor (1965), Associate Professor(1970), and Professor (1977). At the University of Rochester Nuclear Structure Research Laboratory he served as Associate Director (1977-88) and Director (1988-1999). He has held visiting appointments at Laval University, (1965), Niels Bohr Institute in Copenhagen (1973), Lawrence Berkeley Laboratory (1975-76), Australian National University (1978), and the University of Uppsala (1981). He is a Fellow of the American Physical Society. In 2007, he received the Department of Physics and Astronomy Award for Excellence in Undergraduate Teaching.

Prof. Cline has served on government advisory committees including the DOE/NSF Nuclear Science Advisory Committee (1983-89). In addition, he has served on program advisory or executive committees at Brookhaven National Laboratory, Lawrence Berkeley National Laboratory, Oak Ridge National Laboratory, Argonne National Laboratory, Michigan State University; as well as the Editorial Board of Physical Review C. He was a member (1987-91), and chair (1989-91), of the Gammasphere Steering Committee, and member of the Gammasphere Scientific Advisory Committee (1991-95,99). Currently he is serving on the GRETA Advisory Committee.

Research

Prof. Cline's current research interests are in the field of Experimental Nuclear Physics with a focus on nuclear structure. This research program developed powerful techniques, employing heavy-ion induced Coulomb excitation, transfer reactions, and fission, to selectively probe collective shapes, single-particle and pairing degrees of freedom in nuclei as well as neutron-rich nuclei far from stability. Currently this nuclear structure physics program exploits the unprecedented advance in sensitivity provided by the combination of the Gammasphere 4p gamma-ray detector array and Rochester Compact Heavy Ion 4p Counter, CHICO. This work is done in collaboration with groups from Europe and the US. Other facilities, including the combination of the Rochester and Yale gamma-ray detector arrays supplement the Gammasphere-based program. Cline provided essential leadership to the national Gammasphere facility during the critical design period prior to funding and now he is involved in design of the next generation gamma-ray tracking detector array called GRETA.

A scientific thrust of the current research is study of nuclei far from stability, to search for possible significant changes in nuclear structure, elucidate the astrophysical r-process, and study neutron pairing and possible nuclear Josephson effects. Planned radioactive beam accelerator facilities will greatly expand research opportunities for such studies. Another current project is mapping rotational and vibrational collective modes of motion throughout the periodic table to better understand the role played by these important shape degrees of freedom in nuclei. A third scientific goal is the use of nuclei as a laboratory for study of rare double-photon decay.
