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.

Gamma-ray production cross sections were measured for (n, xγ) reactions in natural iron from 0.86- to 16.74-MeV neutron energy using the IRT Linac pulsed-neutron source. The 847- and 1238-keV gamma-ray production cross sections are presented with very high neutron resolution. Also, cross sections for 13 principal gamma rays are given using 20 neutron-energy groups. Cross sections were determined for an additional 16 discrete gamma rays using 10 neutron-energy groups. In general, the cross sections for the discrete gamma rays are in agreement with previous measurements. The gamma-ray spectra for the 10 neutron-energy groups were also unfolded to obtain gamma-ray production cross sections for the sum of both discrete and continuum gamma rays. In the present work the continuum component constituted over half the total gamma-ray production cross sections above 8 MeV.
