Abstract

The prese nt staLe of t Ile a na lysis of the first sp ectrum o f t horium (Th I) is cliscuHsed b ri e Ay . E\'c n fi nd odd levels are listed in t ables 1 and 2. The low even levels [01'111. te r ms a risin g f rom t he co nfi gurations 6d2 782 and 6d3 78. The Th I stalldal'd wavelengths th "t fit into t ile kn o wn level arrays a re presented in table 3.
