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.

Cross sections were measured for the 75As(n,p)75Ge, 75As(n, α)72Ga, 75As(n,2n)74As, 74,76,78Se(n,p)74,76,78As, 78,80Se(n,α)75,77Ge, 72,73,74Ge(n,p)72,73,74Ga, and 70,76Ge(n,2n)69,75Ge reactions over the 6.3- to 14.7-MeV neutron energy range. Samples of As2O3, selenium, and germanium or GeO2 of natural isotopic abundance were used. The neutrons were produced via the D(d,n)3He reaction using a deuterium gas target at a variable energy cyclotron (En = 6.3 to 11.9 MeV) and via the T(d,n)4He reaction using a solid titanium-tritium target at a neutron generator (En = 14.7 MeV). The activation technique was used in combination with high-resolution gamma-ray spectroscopy. The experimental excitation functions are well reproduced by the nuclear model calculations, based on statistical multistep reaction theory.
