This improvement on the zero-order Schmidt moment is compared with previous, smaller first-order corrections calculated with other potentials. A discrepancy with experiment of 0.66 n.m. still remains for this nucleus if one stops at first-order perturbation theory. We also perform complete second-...

The magnetic moment of the nucleus can only be evaluated from hyperfine strucuture observations, and then only in favourable circumstances. The spin quatum number I can sometimes be obtained by bothe methods: by the hyperfine structure method if the magnetic moment and its interaction with the ...
We determine for the first time the magnetic dipole moment of a short-lived nucleus with part-per-million (ppm) accuracy. To achieve this two orders of magnitude improvement over previous studies, we implement a number of innovations int... RD Harding,S Pallada,J Croese,... - 《Physical ...
2.4.3 Magnetic Moment of a Nucleus The magnetic moment of a nucleus is uniquely linked with the orbital moment (2.8)Pm=(e/2me)L. By definition for a negatively charged particle the magnetic moment is opposite in direction to the mechanical moment. Sometimes this is marked by the minus sign...
A strong external magnetic field applied to a radioactive source which emits γ-rays in a cascade process will influence the nuclear spin of the intermediate state and thus change the γ–γ angular correlation. The strength of the interaction is a measure of the nuclear moment and the theory...
1. If the value of the nuclear spin were known, the magnetic moment could be calculated from the above value of ”v by means of Goudsmid's2 formula. In order to find the spin, it is necessary to determine accurately the intensity ratio of the hyperfine structure doublets ; this, however...
while the second, calledmagnetic hyperfine structure, is due to an interaction between the magnetic moment of the nucleus and the electrons. This interaction splits the energy levels of a single isotope into a number of states. Frequently combinations of both types are observed in a single spectr...

The assignment of quantum numbers to the magnetic levels of alkali atoms depends on the sign of the nuclear magnetic moment. If a beam of normal alkali atoms is split in a weak inhomogeneous magnetic field and transitions are then induced among the component magnetic levels, a subsequent strong...
