Investigation of the np ^(2)P_(3/2) Level Sequence in the Cs I Spectrum by Level Crossing Spectroscopy

• Our previous level crossing measurements in the 6, 7, and 8 p 2 P 3/2 levels of Cs 133 have been extended to the 9 and 10 p 2 P 3/2 levels. For the magnetic dipole and the electric quadrupole interaction constants a and b we obtain ##IMG## [http://ej.iop.org/images/1402-4896/5/4-5/010/img1.gif] {figure 1} The natural lifetime of 9 p 2 P 3/2 was found to be 390 (30) ns. The previous analysis for the 6 and 7 p 2 P 3/2 levels is revised, taking new experimental data from this and other laboratories into account. This leads to a better consistency for the quadrupole moments Q for Cs 135 and Cs 137 as evaluated from the 6 and 7 p 2 P 3/2 levels. We obtain Q (Cs 135 ) = +0.052 (4) barn Q (Cs 137 ) = +0.053 (4) barn
