Abstract

The hfs separation Δν of ¹²⁶Cs(T_1/2 = 1.63 m) in the 6s²S_1/2 ground state was obtained in a precision measurement near zero magnetic field by means of atomic beam magnetic resonance with laser optical pumping on-line with the CERN-PSB-ISOLDE mass separator. The result, Δν = 3629.514 (0.001) MHz, corrects significantly a previous published value from a high-field experiment. With our result, the precision of the nuclear magnetic moment, μ(¹²⁶Cs) ≈ 0.776μ_N, is now limited by the influence of extended nuclear structure on the hfs (the Bohr-Weisskopf effect).
