Abstract
A RECENT communication by (the late) S. Heron, R. W. P. McWhirter and E. H. Rhoderick1 on “Measurements of Life-times of Excited States of Atoms by the Method of Delayed Coincidences” was read with much interest here. Their method consists of exciting a source for 2 × 10−8 sec. and observing the intensity of the light emitted by the source at a given time after the excitation. Thus they observe the behaviour of a large assembly of atoms.
