On the relative transition probabilities of rare gases in the 1si–2pj region

We have measured the relative transition probabilities of the 1si–2pj transitions in rare gases using hollow cathode lamps. The emission spectra of each rare gas were recorded as a function of discharge current. Two independent calibration modes for the spectrometer have been used to increase the reliability of our data. Uncertainty in the data have been measured and found to be within ~5%. The relative transition probabilities are reported for 30 lines of Ne I, 25 lines of Ar I, fourteen lines of Kr I, and eighteen lines of Xe I. The present results are in good agreement with the published data. The data can also be used to calibrate the relative detection efficiency of a spectrometer over a range of 400–1000 nm.
