r00].  $^{000}$At {#at-0 .unnumbered} ----------  The paper "$\alpha$-particle branching ratios for neutron-deficient astatine isotopes" by Latimer et al. reported the observation of $^{000}$At in 0000 [@0000Lat00]. Gold and platinum foils were irradiated with 00$-$000 MeV $^{00}$C and 00$-$000 MeV $^{00}$N beams, respectively, from the Berkeley HILAC. Alpha-particle spectra were measured with a gridded ionization chamber following chemical separation. "
