Applications of Detectors in Low Energy Nuclear Physics

This review paper discusses new applications of detectors in low energy nuclear physics and emphasizes semiconductor particle detectors where new developments have had an outstanding influence on the nuclear physics which can be done. The paper includes an account of: new limits of detector resolution; a new method for measurement of gamma ray lifetimes; gamma-gamma angular correlation studies with multiple scintillation detectors; kinematic energy shift correction with radial position sensitive detectors; an improved particle identification system with multiple detectors; and the application of germanium to measurements of long-range charged particles. The paper also discusses present state-of-the-art limitations and possibilities in areas of particular importance to nuclear physics.     

Programs and Systems for On-Line Computers in Low Energy Nuclear Physics

A conference held five years ago this month served, among other things, to introduce the notion to a substantial representation from the community of experimental nuclear physicists that a stored program computer could be used as a powerful, flexible tool for extending the scope of, as well as for aiding in the detailed execution of their experimental programs. The appreciation of the possibilities which were raised were colored by a simultaneous apprehension. The physicists worried about how extensive an effort they would have to make, how intimately they would have to be involved in order to use a computer on-line to an experiment. In short - who was going to write the programs? The answer was, unfortunately, not long in coming - they were. The potential gains for some classes of users were such that they did not wish to leave the restricted world of wired-program analyzers which, after all, were sufficient unto their needs. For others, however, the ends justified the means of the task. This latter group set about creating the programs and, in fact, the systems of programs that were necessary. This paper discusses some of the programming approaches which are in use or are under development for handling all or some features of experiment procedures. Because this conference has reports directly by several of the users, the emphasis here will be to review and compare rather than describe any in great detail.     

Investigation in Possibility of Producing Superheavy Fragments Through Massive Nuclear Reactions at Low Energies

In this paper, the possibility of producing superheavy fragments through composite system breaking up in massive nuclear reactions is investigated. Two main theoretical models, which are the quantum fluctuations within the fragmentation theory developed at 80 years and improved quantum molecular dynamics model developed recently by our group,
