The two groups are Emanuel Maxwell, who published his results in Isotope Effect in the Superconductivity of Mercury and C. A. Reynolds, B. Serin, W. H. Wright, and L. B. Nesbitt who published their results 10 pages later in Superconductivity of Isotopes of Mercury.
Neid kahte rühma juhtisid Emanuel Maxwell, kes avaldas enda tulemused artiklis "Isotope Effect in the Superconductivity of Mercury" (Isotoobi efekt elavhõbeda ülijuhtivuses), ja C. A. Reynolds, B. Serin, W. H. Wright ning L. B. Nesbitt, kes avaldasid oma tulemused 10 lk tagapool artiklis "Superconductivity of Isotopes of Mercury" (Elavhõbeda isotoopide ülijuhtivus).
