Abstract:

Recent approaches to the problem of the gamma ray laser have focused upon upconversion techniques in which metastable nuclei are pumped with long wavelength radiation. At the nuclear level the storage of energy can approach tera-Joules per liter for thousands of years. This report focuses upon a variety of new technologies to demonstrate feasibility benefitting from the strong momentum realized already along the approach to incoherent pumping, most continued to advance the development of the nuclear analog of the ruby laser. A unique type of Compton spectrometer was brought into service during this reporting period. The greatest breakthrough was realized along the more complex approach of coherent pumping. There it is intended to mix the quantum properties of long-lived isomeric states with those of freely radiating nuclear levels. Contents Thermal economy of a gamma ray laser Determination of gateway states in Au 197 with a compton gamma ray spectrometer Limits on neutron activation interferences in photoactivation cross-section measurements in the 1.5-6 MeV range A flash x-ray source excited by stacked blumlein generators Preliminary study of a laser ion source for growing diamond-like carbon films and Large scale effects of the magnetic phase modulation of recoilless gamma transitions.
