Experimental Nuclear Physics: Intermediate energy polarized proton and deuteron scattering. Spin-isopin response function in
nuclei. Photonuclear reactions.
Most of our research is supported by the National Science Foundation and is carried out at different locations. The spin-flip
transition in nuclei are studied by inelastic scattering of polarized protons and deuterons at the National Laboratory SATURNE in
Saclay, France. The isoscalar spin-flip strength has been measured for the first time in the continuum of medium heavy nuclei using
400 Mev polarized deuterons. The spin transfer observable has turned out to be a robust observable making these measurements
extremely successful. This program will be extended to the study of baryonic resonances.
Photonuclear reactions such as the photo disintegration of the deuteron, the E2/M1 ratio of the delta and the polarizabilities of
the proton and neutron, are presently carried out at the Laser Electron Gamma Source (LEGS) facility at the Brookhaven National
Laboratory. We are also studying the photoproduction of neutral mesons at the ELSA facility in Bonn, Germany. We are
participating in the large Acceptance Spectrometer collaboration at CEBAF (Virginia). We will also participate in the Grenoble
Anneeau Accelerateur Laser (GRAAL) Collaboration in France. The fully polarized gamma rays (up to 1.5 Gev) in energy will
allow us to study the production of strange particles. Most of our graduate students perform their research at these different facilities.
