Abstract

A highly sensitive method of spectrographic detection of gases was used to detect the absorption of atomic astatine. Two lines were recorded whose wavelengths were 2244.01 and 2162.25 Å. These lines were tentatively assigned to the transitions $²{P_{\frac{3}{2}}}^0-⁴P_{\frac{5}{2}}$ and $²{P_{\frac{3}{2}}}^0-⁴P_{\frac{3}{2}}$ between configurations 6p⁵ and 6p⁴ 7s. The assignment of two resonant lines of polonium was confirmed.
