在4~120帕的压力范围内，研究了中性氙气中双光子激发的8p，9p，J=0，2能级和5f，6f，J=2能级的激光诱导荧光。用Stern-Volmer方法计算了5f[3/2](2)、5f[5/2](2)和8p[1/2](0)能级的辐射寿命和碰撞失活率。5f[3/2](2)、5f[5/2](2)和8p[1/2](0)能级的自发寿命分别为94、78和207 ns。用扩展的多组态Dirac-Fock波函数计算了这些寿命，结果与实验符合10-25%。
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 %.
