Abstract
Absolute transition probabilities are measured for 24 prominent Ge I and Ge II lines between 3200 and 6500 Å. Spectroscopic plasmas are generated by the shock heating of neon or argon containing (0.2-2.0)% Ge to temperatures 10 200-12 600° K at pressures of (6-32) × dyn . To reduce possibilities for bias, the state of the light source and the integrated energy of emitted lines were determined redundantly. values were measured by methods inherently insensitive to possible temperature errors. Ionic transition probabilities [estimated accuracies (23-50%] are compared with central-field approximations and are tested for conformity with quantum-mechanical sum rules. Neutral germanium data [accuracies (30->50)%] are compared with other experimental results.
