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.

From symmetric meson theory, the formation of helium nucleus from two deuterons, i.e., fusion, requires necessarily a direct force due to exchange of two neutral pions, which do not actually compose the deuteron nucleus. The neutral pions are provided by two photons, which are produced by emission of excited collective electrons derived from the palladium atoms. The introduction of the pions makes it possible to reduce remarkably an internuclear distance, enhancing the fusion rate for helium formation. The dynamic interaction is interpreted as the result of condensation of deuterons into octahedral interstitial sites by electrolysis and contraction of the deuteron octahedra around the Pd10- atom with the help of the electron-phonon charge-density wave coupling.
