摘要:

本文用相对论SD近似计算了T1 I中6P_(1/2)-7 P_(1/2)跃迁的斯塔克诱导振幅。SD值α S = 368 a0 3和β S= 298 a0 3与D的测量值α S=377(8)a0 3$和β S = 313(8)a0 3符合得很好。DeMille,D. Budker和E. D. Commins [Phys.Rev.A50,4657(1994)]。计算了6P_(1/2)-7 P_(1/2)和6P_(1/2)-7S_(1/2)跃迁的斯塔克位移。我们的计算预测的斯塔克位移同意最准确的测量值的实验不确定性内的两个过渡。

英文摘要:

Stark-induced amplitudes for the 6P1/2 - 7P1/2 transition in Tl I are calculated using the relativistic SD approximation in which single and double excitations of Dirac-Hartree-Fock levels are summed to all orders in perturbation theory. Our SD values alpha S = 368 a0 3 and beta S= 298 a 0 3 are in good agreement with the measurements alpha S=377(8) a 0 3$ and beta S = 313(8) a 0 3 by D. DeMille, D. Budker, and E. D. Commins [Phys. Rev. A 50, 4657 (1994)]. Calculations of the Stark shifts in the 6P1/2 - 7P1/2 and 6P1/2 - 7S1/2 transitions are also carried out. The Stark shifts predicted by our calculations agree with the most accurate measured values within the experimental uncertainties for both transitions.
