But additional dynamical forces, long known to exist in nuclei, cannot be understood with elementary particles alone, just as new cooperative interactions, not recognizable in nuclei or atoms, are known to exist in macroscopic materials. The basic questions facing nuclear physics today span a broad range, including strong and electroweak interactions, and cover the properties of the physical world from the microscopic scale of nuclear forces to the large-scale structure of the universe.

The use of high-energy electron scattering from nuclei has revealed unprecedented levels of detail of nuclear structure, in terms not only of the nucleons but also of the mesons present in nuclei and, to a rudimentary degree, of the quarks that compose all of these particles. Such studies represent one of the major frontiers of nuclear physics today.

, as well as many routine industrial applications (including, for example, well-logging in test bores using miniaturized nuclear accelerators, food preservation by irradiation, and die hardening by ion implantation to reduce wear) , and even the analysis of art objects are just a few examples of how the fruits of nuclear-physics research have found a multitude of useful and sometimes surprising applications in other basic sciences and in modern technologies, many of which have direct and significant impacts on society at large.

The Planned Continuous Electron Beam Accelerator Facility In April 1983, NSAC recommended the construction of a 100percent-duty-factor, 4-GeV linear-accelerator/stretcher-ring complex now called the Continuous Electron Beam Accelerator Facility (CEBAF) , which was proposed by the Southeastern Universities Research Association.

The only conceivable way at present of producing the conditions necessary for achieving quark Reconfinement is to collide the very heaviest nuclei head-on at relativistic energies, thereby creating enormous nuclear temperatures and energy densities throughout the relatively large volume of the two nuclei. The ability of quarks and gluons to move about within this volume will enable fundamental aspects of quantum chromodynamics at large distances to be tested.

Additional Facility Opportunities The major questions currently facing nuclear physics, including nuclear astrophysics, point to a number of important scientific opportunities that are beyond the reach of the experimental facilities either in existence or under construction. Many of these opportunities might be realized through a variety of upgrades and additions to the research capabilities of existing facilities, and it appears that a reasonable fraction of them could be achieved within the base program envisioned at present.

Progress in current theoretical research depends on substantial access to first-class computational facilities. Extensive calculations based on the complex models describing today's experiments require the large memories and rapid processing capabilities of Class VI computers.

From page 8... ...
To meet these needs and to continue to explore the basic research opportunities in nuclear physics, a steady influx of first-rate young scientists to our universities, national laboratories, and industries is essential. The Panel is concerned about the continuing decline in the number of students pursuing graduate courses in physics, and nuclear physics in particular.
