✦ Synopsis

The relative intensities of 80 emission lines in 16 multiplets of iron, in the spectral region A 3800/1_--5300 A have been measured. Light source is a King furnace with a graphite tube at a temperature of 2800°K as heating element. The spectrograph is a concave grating in Wadsworth mounting, the recording apparatus a photomultiplier with a linear amplifier and tube voltmeter.

The f-values derived from the measured intensities are compared with the/-values obtained by R. B. and A. S. K i n g from measurements in absorption.
