Abstract
PREVIOUS experimental work on the measurement of the life-times of atomic energy states has been subject to error mainly due to the inaccuracy of vapour pressure data. A magnetic rotation method devised by Weingeroff1 which eliminates the vapour pressure in the final expression for the life-time has apparently been overlooked. This method has recently been employed here2 for the measurement of the life-times of certain atomic resonance states; a detailed account of the method will be given in a later paper; but it was felt that the following results would be of interest at the present time.
