ATOMIC OSCILLATOR-STRENGTHS FROM EMISSION MEASUREMENTS - ACHIEVEMENTSAND LIMITATIONS

Emission spectroscopy as one of the standard methods to measure atomic transition probabilities is discussed with its advantages, its restri ctions and its pitfalls. The measurement of branching fractions combin ed with lifetime data obtained with modern laser techniques is discuss ed as the prevailing measuring procedure which guarantees large sets o f reliable f-values. The trend to shorter wavelengths in astrophysics and in fusion research will also in the future keep emission spectrosc opy attractive.
