Spectrum of Trebly Ionised Lead
Abstract
THE spectrum of trebly ionised lead, which has been studied by several authors ending with S. Smith1, requires modification in several respects. I have shown that 7p2P-7d2D is really 7p2P-8s2S and confirmed this by obtaining further combinations with the 8s2S term. This provides a series of 2S terms the values of which can be accurately calculated by Hicks's formula. 6s2S comes out equal to 340180, giving an ionisation potential of 41.9 volts.
