Hash Hashemian: Visionary leadership
As Dr. Hashem M. “Hash” Hashemian prepares to step into his term as President of the American Nuclear Society, he is clear that he wants to make the most of this unique moment.
A groundswell in public approval of nuclear is finding a home in growing governmental support that is backed by a tailwind of technological innovation. “Now is a good time to be in nuclear,” Hashemian said, as he explained the criticality of this moment and what he hoped to accomplish as president.

A photoexcitation process by gamma rays from a 60Co source has been studied for the nuclei of 87Sr, 111Cd, 115In, and 176Lu. The induced isomeric activity was measured with a Ge(Li) detector. The flux of photons scattered into the target has been estimated with the Monte Carlo method using the single-scattering approximation. From the observed induced activities and the calculated photon flux, the integral cross sections for isomer production by photoexcitation were obtained and compared with other experimental data.
