.  $^{000,000}$Rn {#rn-00 .unnumbered} --------------  Meinke et al. reported the observation of $^{000}$Rn and $^{000}$Rn in the 0000 paper "Three additional collateral alpha-decay chains" [@0000Mei00]. Thorium was bombarded with 000$-$000 MeV $^0$He beams from the Berkeley 000-inch cyclotron. Alpha-decay chains from $^{000}$U and $^{000}$U were measured following chemical separation. "The irradiation of thorium with 000-Mev helium ions resulted in the observation of the following collateral branch of the artificial 0n$+$0, neptunium, radioactive family shown with Po$^{000}$ and its decay products: $_{00}$U$^{000}\overset{\alpha}{\rightarrow}_{00}$Th$^{000}\overset{\alpha}{\rightarrow}_{00}$Ra$^{000}\overset{\alpha}{\rightarrow}_{00}$Em$^{000}\ldots$ Immediately after 000-Mev helium ion bombardment of thorium the uranium fraction contains another series of five alpha-emitters, which is apparently a collateral branch of the 0n family: $_{00}$U$^{000}\overset{\alpha}{\rightarrow}_{00}$Th$^{000}\overset{\alpha}{\rightarrow}_{00}$Ra$^{000}\overset{\alpha}{\rightarrow}_{00}$Em$^{000}\ldots$" In a table summarizing the energies and half-lives of the decay chain only the $\alpha$-decay energ
