Abstract The level crossing method has been used for the investigation of the hyperfine structure of the 6p2P3/2 and 7p2P3/2 levels of the isotopes Cs133, Cs135, and Cs137. For the hyperfine coupling constants a and b and for the lifetimes Τ we find: a(6p Cs133)=50.72(3) gJ/−1.345, b(6p Cs133)=−0.38(18) gJ/−1.345 a(7p Cs133)=16.610(6) gJ/−1.3349, b(7p Cs133)=−0.15(3) gJ/−1.3349 a(6p Cs135)=53.64(4) gJ/−1.345, b(6p Cs135)=7.41(32) gJ/−1.345 a(7p Cs135)=17.570(6) gJ/−1.3349, b(7p Cs135)=2.35(7) gJ/−1.3349 a(6p Cs137)=55.80(4) gJ/−1.345, b(6p Cs137)=7.54(20) gJ/−1.345 a(7p Cs137)=18.274(6) gJ/−1.3349, b(7p Cs137)=2.37(4) gJ/−1.3349 (MHz), Τ(6p2P3/2)=29.7(2) −1.345/gJ ns, Τ(7p2P3/2)=135(1) −1.3349Jns. From a comparison with double resonance results the gJ factor of the 7p2P3/2 level was deduced: gJ(7p2P3/2=−1.3349(10). Level crossing measurements in the 8p2P3/2 state of Cs133 give for the gJ factor and the lifetime the following results: gJ(8p2P3/2)=−1.3353(14), Τ(8p2P3/2)=310(15) ns. Using recently calculated relativistic correction factors and applying corrections for core polarization and the Sternheimer effect, we obtain for the quadrupole moments: Q(Cs133)=−0.0030 b, Q(Cs135)=+0.052 b, Q(Cs137)=+0.052 b.
