." This value is consistent with the currently adopted value of 00.0(0) min. About three months earlier Miller et al. [@0000Mil00] measured an 00 min half-life by bombarding a gold target with a $^{00}$C beam and suggested the possibility that they had formed the 00 min $^{000}$At activity based on a private communication with Barton et al.  $^{000}$At {#at-00 .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. "
