Abstract : Studies of the 29 possible candidates to use as the working medium of a gamma ray laser have identified the 31-year isomer of Hafnium-178 as the best. This research is aimed at the development of a production cycle for this rare substance. A major success of this year's work has been the discovery in byproduct debris from the synthesis of medical isotopes of a quantity of this material equal to 99% of the world's inventory. Chemical conditioning and recovery of this sample have been initiated. Also, an evaluation was made of the 142 reactions with potential for restocking the existing inventories. (AN)
