Phys. Rev. E 80, 026401 (2009) [6 pages]Time-resolved fluorescence spectroscopy of two-photon laser-excited 8p, 9p, 5f, and 6f levels in neutral xenonReceived 14 April 2009; published 6 August 2009 Laser-induced fluorescence of two-photon excited 8p, 9p, J=0,2 and 5f, 6f, J=2 levels in neutral xenon has been investigated in the pressure regime between 4 and 120 Pa. Radiative lifetimes and collisional deactivation rates have been deduced especially for the 5f[3/2]2, 5f[5/2]2, and 8p[1/2]0 levels using the Stern-Volmer approach. The spontaneous lifetimes for 5f[3/2]2, 5f[5/2]2, and 8p[1/2]0 levels are 94, 78, and 207 ns, respectively. These lifetimes have been calculated also by applying extended multiconfiguration Dirac-Fock wave functions and are found in agreement with experiment within 10–25 %. © 2009 The American Physical Society URL:
