The Yale program in heavy ion physics is a relatively broad one involving experimental work on both the MP tandem Van de Graaff and the HILAC linear accelerator. The work on the HILAC is under the direction of Professor John Rasmussen and focusses on a broad range of nuclear spectroscopic studies of the (H.I, xny) variety as well as on searches for double proton radioactivity and other more specialized topics. On the MP tandem there are a variety of different programs; Professor Greenberg is involved in a continuing program of studies centering on heavy ion induced Coulomb excitation; Professor Stokstad has worked on extension of heavy ion induced Doppler shift techniques to heavy targets and is involved with Professor Bromley and myself in studies of cluster transfer reactions leading to what we believe may be quartet states in sd shell nuclei; Professor Bromley has begun studies on the population of very high spin states in light nuclei through heavy ion reactions and together we have been continuing and expanding the Yale program of heavy ion scattering with our colleagues. A new, more powerful theoretical approach to the study of coupled channel situations which we have encountered in this work is being developed. It is this last area of study which is particularly appropriate to this symposium and I shall concentrate upon it in the time available. Early work in this relatively new field not surprisingly was primarily of an exploratory and often qualitative nature directed toward a crude mapping of the nuclear areas most susceptible to this new attack. More recently, however, precise quantitative measurements of data are becoming available from laboratories throughout the world and it becomes essential that these new data be subjected to the detailed microscopic analyses long characteristic of reaction studies with the more traditional nuclear projectiles.
