We have continued to develop a theoretical framework for the quark and gluon structure of nuclei. We have also shown that a consistent treatment of relativistic effects is important for a theoretical description of the elastic magnetic form factor of /sup 17/O. These results motivate a new investigation of the temperature dependence of the ion-ion potential with particular emphasis on the thermal dependence of the barrier height and radius. In addition we have completed a set of predictions for the formation of a ''nuclear stratosphere'' in nuclei created by intermediate energy heavy ion interactions. We have completed our development of a parameterized thermal liquid drop model for light nuclei. We have completed our analysis of the SLAC E101 and E133 experiments on Deuterium to elucidate the degree to which a six-quark cluster contribution is admissable in the Bjorken x > 1 data. We propose to continue predicting phenomena to be observed in high energy particle-nucleus collisions that reflect the rearrangement of quarks and gluons in nuclei. Simultaneously with this new effort we will continue to develop extensions and applications of the QCM. We propose in subsequent years to address QCD in low dimensionality with the purpose of extracting non-perturbative predictions for quark and gluon amplitudes in few baryon systems. We now propose to solve the same problem for simple Fermion field theories more » in 2D such as the Gross-Neveu model. By the explicit example of a scalar field theory in 2D we have solved the long-standing problem of how to treat the dynamics of the vacuum in light-front quantization. The effort in quantum field theory provides theoretical results to test or replace assumed ingredients of the QCM. Our approach features a successful phenomenological model, the quark cluster model (QCM), and an ambitious program in the non-perturbative solution of quantum field theories. We also propose to continue our efforts to develop nonperturbative methods to solve quantum field theories with fermions both on the light-front and with equal time quantization. We propose a strong effort in the direction of eventually solving relativistic three-body wave equations for a model of the baryons. Although we have much progress to report, many outstanding problems remain. In discovering this resonance phenomena we have uncovered a new scale for phenomena within QED. Resonances are obtained which are in accord with the electron-positron peaks observed in the GSI heavy-ion experiments. An important spin-off from the relativistic two-body wave equation effort has been the solution of QED for electron-positron scattering which is complete through the order of one-photon exchange. Two prominent examples are the development and solution of relativistic two-body wave equations for bound states and resonances and the development of methods for solving field theories via more » light-front quantization which include the treatment of a dynamical vacuum. Our primary emphasis in field theory continues to be the solution of non-perturbative problems.
