Abstract:

Youngstown State Universitys Isomer Physics Project is a program of basic physics research with the goal of providing credible, high-quality measurements and theoretical analysis related to achieving a controlled release of energy stored in nuclear isomers. An emphasis has been on providing a firm foundation coupling traditional nuclear structure research, such as in spectroscopic studies, with focused triggering experiments. As such, success is defined not by proving or disproving specific preconceptions, but by obtaining the best possible insight into physical reality. Under the present contract, and as part of the DARPA SIER program during its first year, effort was concentrated on examining the possibility of triggered gamma emission from the 31-year isomer of 178Hf. This effort was divided into three distinct areas, two experimental and one theoretical. This report describes results obtained in these areas. At this point, no support was found for claims of triggering of 178 sq cmHf near 10 keV.
