We propose to perform a series of experiments involving nuclear isomers which will investigate the probabilities and mechanisms for de‐exciting the isomeric level down to the ground state upon exposure to external radiation in the form of fast neutrons and bremsstrhalung x rays. The isomers have half‐lives on the order of 1 hr to 10 days which is a convenient time scale to measure statistically meaningful changes in the specific activities of the isomeric state. Furthermore, the selected isomers are relatively easy to produce in our laboratory in sufficient quantities so that they can be made in a reasonable time frame and without recourse to any exotic means of production, handling or preparation and without the need for high‐purity separated isotopes as the feedstock. We believe that studies undertaken in this fashion will produce fundamentally valuable information on the factors which govern and influence “forced‐gamma emission” in nuclear isomers This type of information will potentially be very useful in similar studies involving longer‐lived isomers such as:178m2Hf, 242mAm and 108mAg which have the potential to be used in various emerging new technologies in the later part of the 21st Century.
