Finally, a search for PV in the helicity dependence of the deuteron photodisintegration cross section, which is becoming practical with the development of the high intensity gamma source (HIGS) laser backscattering gamma facility at the Triangle Universities Nuclear Laboratory (TUNL), would be sensitive to the [.sup.1][S.sub.0] [right arrow] [.sup.3][P.sub.0] and [.sup.3][S.sub.1] [right arrow] [.sup.1][P.sub.1] amplitudes.
Nuclear Solutions' flagship, proprietary technology, the HYPERCON(TM) ADS process, is an X-ray based photodisintegration process, which in currently in development as a possible new application for the remediation of nuclear waste.
Technically speaking, what is commonly referred to as x-ray absorption is more correctly called x-ray attenuation, which includes photoelectric absorption, incoherent (Compton) scattering, pair production, coherent (Thomson, Rayleigh) scattering, and photodisintegration [8].
