Fluorescence of Na-2 excited by the 4545 angstrom line of the argon ion laser

The fluorescence spectrum of Na-2 induced by the blue 4545.05 Angstrom line of an argon ion laser has been observed and analysed for the first time. Four fluorescence series excited through the transitions: v' = 20, J' = 51 <-- v '' = 2, J '' = 50; v' = 27, J' = 71 <-- v '' = 4, J '' = 71; v' = 18, J' = 48 <-- v '' = 1, J '' = 47 and v' = 17, J' = 58 <-- v '' = 0, J '' = 57 were assigned in the (BIIu)-I-1 --> X(1) Sigma(g)(+) band system. The calculated radiative transition probabilities for the observed fluorescence series are in good agreement with measured relative intensities reported herein. Copyright (C) 1996 Elsevier Science Ltd
