Abstract
DURING the recording of the spark spectrum of americium1 in the third order of the Baird three-metre grating spectrograph, a number of spectral lines appeared as four resolved components of a probable six-member flag pattern. While describing the performance of a 30-ft. Paschen–Runge spectrograph, Tomkins and Tomkins2 have published a photograph of the Am I line at 6405 A. showing it resolved into six components. The six component flag patterns, which lead to a nuclear spin of 5/2 for 95Am241, have been confirmed by interferometric studies.
