title = "Nuclear magnetic moment of 203Hg by optical pumping",
abstract = "Optical-pumping techniques have been used to obtain a direct measurement of the nuclear magnetic moment of the 47-d radio-isotope 203Hg. The result is (203μ)uncorrected 0.83549 (13) μN. The effect of distributed nuclear magnetization gives an hfs anomaly 203Δ201 = 0.0064 (2).",

note = "Funding Information: We have used optical pumping \[1\] to obtain a direct measurement of the nuclear magnetic moment of the 47-d radioisotope 203Hgo The exploitation of the great sensitivity of optical techniques for studying nuclear magnetic resonance In very small samples, and in particular in artificially produced radioisotopes, was first suggested by Bitter \[2\]° Samples as small as 1012 atoms have been studied successfully. The optical pumping method relies on the transfer of angular momentum from photons of the incident resonance radiation to atoms in a vapor. An unequal population among the Zeeman sublevels of the atoms in a magnetic field is thereby created. The unequal population serves to detect paramag-netlc resonance either through a change In the transparency of the atoms to the resonance radiation or through the observation of modulation on a probing light beam that results from their Larmor precession, Wo, in the externally-applied magnetic field. We used the latter method, which was proposed by Dehmelt F3\] and first demonstrated by Bell and Bloom \[4\]. By Carver and Partridge \[5\] it was shown, with the use of the density-matrix formalism, that under Dehmelt's conditions the signal, S, should be * Supported by the National Science Foundation Grants GP 7919, Gp 15258, in part by the James Arthur En-dowment Fund of New York University, and an equip-ment grant DA-ARO-D-31-124-G763 from the Army Research Office. ~:On leave September 1969-September 1970 at the Labo-ratoire Almd Cotton, C.
