GRC found that repeatable sub-threshold nuclear reactions may have occurred resulting in nuclear products observed via witness-material neutron activation using high purity germanium (HPGe) gamma spectroscopy and liquid scintillator spectroscopy. The suspected path of creation may be the result of electron-screened Oppenheimer-Phillips reactions or Mirror Oppenheimer-Phillips reactions. Evidence of 162Er(d, n)163Tm or 162Er(p,γ)163Tm has been shown with the appearance of gamma peaks coinciding with 163Tm with a published ' life of 22 minutes from samples containing deuterated erbium exposed to a photon beam. Both of these reactions are a variation of the Oppenheimer-Phillips nuclear reaction. Evidence of the reactions have been detected by an HPGe gamma detection system and witnessed within gamma spectra collected from deuterated materials subjected to a nominally 1.95 MeV photon beam. This paper describes the theory behind the proposed reactions, the experiments conducted at GRC, and the experimental evidence of the suspected creation of the 163Tm isotope.
