Abstract : Through strong excitation of atomic hydrogen with direct current of 0.2 to 1 amp per square centimeter, anomalous dispersion of H(alpha) and H(beta) is produced and measured photographically. The ratio of the 'number of dispersion electrons' that results is 4.7. This ratio in the first approximation, according to the quantum-theoretical dispersion formula, is equal to the strength of the resulting quantum transition, that is, essentially it is equal to the transition probability. According to quantum mechanics, one calculates herewith the value of 5.37. The variation from the measured value lies somewhat outside of the expected variation, but can be explained by the influence of the negative dispersion, which apparently cannot be disregarded with such intense excitation of hydrogen.
