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.

Calculations of the differential photon-production cross sections from proton-nucleus collisions in the energy range 15 to 150 MeV have been carried out and compared with experimental measurements on 12C, 16O, 27Al, and 56Fe. The calculations are based on the intranuclear-cascade-evaporation model of nuclear reactions and simple assumptions about the deexcitation of excited nuclei. The calculated total photon-production cross sections are within roughly a factor of two of the experimental values, but the calculated photon spectra are not in good agreement with the experimental spectra.
