Level-Crossing-Untersuchung der Hyperfeinstruktur von Sn117 und Sn119 im (5p6s) 3P1 0-Term des Sn I-Spektrums

Using the level-crossing technique the following relations between the hyperfine structure constant A and the gj value of the (5p6s)3P1 0-term were determined for both the stable isotopes Sn117 and Sn119: A117 = — 159,57(4) mK · gJ/1,380; A119 = — 167,01(4) mK · gJ/1,380. From the width of the level-crossing signal a mean lifetime τ = 4,5(7) · 10-9 sec was deduced.
