Hyperfine Interaction, Zeeman and Stark Effects for Excited States in Rubidium
(1976) In Physica Scripta 13(6). p.351-362- Abstract
- Highly excited P and D states in 87 Rb were examined using a two-step excitation procedure. A conventional rf lamp and a CW dye laser were used for the first and second step, respectively. The following results for the magnetic dipole interaction constant a , the electric quadrupole interaction constant b , the Landé g J factor, and the tensor polarizability α 2 were obtained in level-crossing and optical-double-resonance experiments: 9 2 P 3/2 : a = 4.05(3) MHz, b =0.55(3) MHz, g J = 1.3335(15) 10 2 P 3/2 : a = 2.60(8) MHz, g J = 1.3332(20) 8 2 D 3/2 : a = 2.840(15) MHz, b = 0.17(2) MHz 8 2 D 5/2 : a = -1.20(15) MHz, g J = 1.1998(15) 9 2 D 3/2 : a = 1.900(10) MHz, b = 0.11(3) MHz 9 2 D 5/2 : a = (-)0.80(15) MHz, g J = 1.1995(15), α 2 =...

The polarization effect is included to all orders, whereas the correlation effect is omitted. The negative a factors for the 2 D 5/2 states, indicating large perturbations, are explained by the polarization contribution. A review of experimental hyperfine interaction constants, Landé g J factors and tensor polarizabilities for rubidium is given together with theoretical values of the a factors. The quadrupole moment for 87 Rb is obtained from the b factors for the 2 P 3/2 and 2 D 3/2 states, using quadrupole parameters from the many-body calculations. The correlation effect is included in a semi-empirical way. (Less)
