Precise description of the odd parity energy levels in the spectrum GeI

A fine structure analysis for the system 4s24pn's (n'=5 to 14) + 4s24pn''d (n=4 to 14) + 4s4p3 is performed on the basis of available experimental data. The Slater integrals and spin-orbit parameters are determined. The configuration 4s4p3 is shown to influence strongly the odd level system of GeI. On the basis of the theoretical results precise spectroscopic assignments of 154 odd parity electronic energy levels are given. The quantum numbers n' and l' for excited electron states fail to be good quantum numbers in many cases. (orig.)
