A rarely studied feature of many naturally abundant isotopes is the possibility of exciting the nucleus using high energy photons into an isomeric state with a half-life of microseconds up to minutes and hours. These photonuclear interactions have been explored as a method of performing non-destructive trace elemental analysis of mineral ores using a technique known as Gamma Activation Analysis (GAA). In GAA, samples are irradiated with a linear accelerator to induce short-lived radioactivity in a sample, transferred to a shielded pair of high purity germanium detectors where their characteristic decay is measured. The time taken to mechanically transfer samples precludes the measurement of isomers with half-lives shorter than a second, which requires any measurement apparatus for these isomers to be near the intense exciting radiation and measure between rapid accelerator pulses. The production cross sections for these isomers do not exist in experimental reaction databases, and sever
