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]{sub 2}, 5f[5/2]{sub 2}, and 8p[1/2]{sub 0} levels using the Stern-Volmer approach. The spontaneous lifetimes for 5f[3/2]{sub 2}, 5f[5/2]{sub 2}, and 8p[1/2]{sub 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%.
