Abstract

The nuclear Zeeman levels of the ground state of Barium (6s2 1S0, F=I=3/2) were polarized by means of optical pumping with the resonance line (6s2 1S0−6s 6p1P1, λ=5535 Å). The magnetic field was calibrated by means of optical pumping of sodium. The magnetic moments, calculated from the nuclear Hf-Zeeman-transitions at 228 Gauss are μ135=0,83651 (6) μN μ137=0,93573 (6) μN (with diamagnetic correction).

With the results of nuclear induction in BaCl2 we calculate the chemical shift to be (8.6±1.0)·10−4.

The ratio of the nuclear moments is μ137/μ135=1.11862 (3) in agreement with the measurements in BaCl2.
