Abstract
The lowest-lying radiative state of barium chloride has been studied by las er-induced fluorescence in the near-infrared wavelength region. The A (II1/ 2)-I-2 and A (II3/2)-I-2 states have been investigated in time-resolved exp eriments using a Ti:Sapphire laser. The zero pressure radiative lifetime me asured for the e-levels of BaCl was 107 +/- 4 ns for the A (II1/2)-I-2 stat e and 101+/-6 ns for the A (II3/2)-I-2 state. The discrepancy between the c orresponding transition moments is discussed. (C) 2000 Elsevier Science B.V . All rights reserved.
