Natural Radiative Lifetimes of the 5p6s^(1)P_(1) , 5p6s^(3)P_(1,2), and 5p5d^(3)D_(1,2,3) Levels of the Sn I Spectrum by Zero Field Level Crossing Spectroscopy

• Natural radiative lifetimes of some excited levels belonging to the 5 p 6 s and 5 p 5 d configurations have been measured by the Hanle method. Some of the levels could be optically excited only from the metastable 3 P 1 and 3 P 2 levels of the 5 p 2 ground configuration. These comparatively low-lying levels were sufficiently populated at the temperature necessary to produce a Sn atomic beam. The following results were obtained: Ï(5 p (3/2)6 s 1 P 1 ) = 4.11 (22) ns Ï(5 p (1/2)5 d 3 D 1 ) = 3.9 (5) ns Ï(5 p (1/2)6 s 3 P 1 ) = 4.75 (18) ns Ï(5 p (1/2)5 d 3 D 2 ) = 5.5 (4) ns Ï(5 p (3/2)6 s 3 P 2 ) = 4.25 (23) ns Ï(5 p (1/2)5 d 3 D 3 ) = 5.8 (6) ns These values are compared with the results from other types of investigations.
