“…The accuracy of these measurements is estimated as i 8 per cent. The energy thus obtained for the Agll2 betaray favors distinctly the value reported by Seller (7) and that found for Agl-^3 is in good agreement with the values reported by DuffleId and Knight (8) and by Turkevlch,(9).…”

“…The similarity of the energy levels suggest the mass number 114 for the 2.4-min Pd, 5-sec Ag chain." This half-life agrees with the presently accepted value of 4.6(1) s. The previous observation of a 2 m activity [41] could not be confirmed. 115…”

“…In the 1949 paper Radioactive Isotopes of Silver Produced by Photo-Disintegration of Cadmium, Duffield and Knight reported the discovery of 115 Ag [41]. Cadmium oxide enriched with 116 Cd was bombarded with 21 MeV betatron x-rays at the University of Illinois.…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
