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.

Estimated cross sections for neutron production from triton bombardment of gold are deduced from measurements of triton interactions with gas targets that used gold as a triton beam stop material. Differential cross sections for production of neutrons from 5.97-, 7.47-, 10.45-, 16.41- and 19.14-MeV tritons on 197Au were evaluated. Corrections for the neutron interaction in gold, in the target structure, and in the air of the flight path were obtained by means of a Monte Carlo technique. Uncorrelated scale uncertainties range from 24% to 41% whereas those of double-differential cross sections range from 0.2% to 5%. Based on these cross-section data, calculation of neutron yield at 0 deg from fully stopped tritons at 20.22 MeV agrees with an independent measurement. Least-squares fits with a gamma distribution model indicate an anisotropy in the high-energy portion of the neutron spectra. Legendre polynomial fits of differential cross sections are reported. All neutron cross-section data are made available through the Experimental Nuclear Reaction Data (EXFOR) library at international data centers.
