    "abstract": "The off-diagonal hyperfine interaction between the 6p1/2 and 6p3/2 states in\n133Cs is evaluated in third-order MBPT giving 37.3 Hz and 48.3 Hz,\nrespectively, for second-order energies of the 6p3/2 F=3 and F=4 levels. This\nresult is a factor of 10 smaller than one obtained from an uncorrelated\nfirst-order Dirac-Hartree-Fock calculation and used in the analysis of a recent\nhigh-precision (\u003c 2 kHz) measurement of the 6p3/2 hyperfine structure [Gerginov\net al. Phys. Rev. Lett. 91, 72301 (2003)]. The factor of 10 difference has\nnegligible effect on the conclusions of the recent experiment but will become\nimportant for experiments carried out at a precision of better than 1 kHz.",
