For the magnetic moment of the 2083 keV level of 140 Ce, there are four published data, all obtained by applying an external magnetic field of less than 5 T to a liquid sample containing 140 La using the time-differential perturbed angular correlation (TDPAC) technique. Although these four values are consistent within two times their uncertainties (2σ ), the range of values in 2σ extends from μ = +3.0 to + 5.2 (in units of nuclear magneton, μ N ). This time, the TDPAC technique was successfully applied to the 2083 keV level of 140 Ce implanted in an Fe foil. The magnetic moment of this level was determined to be μ = +4.00(20)μ N , employing the known hyperfine field at 141 Ce in Fe, − 41(2) T, which agrees very well with one of the values, μ = +4.06(15)μ N . The present value is compared with two shell-model calculations.
