Effects of the Distribution of Nuclear Magnetization on Hyperfine Structure

The theory of the effects of the distribution of nuclear magnetization is discussed with a view to distingnishing between the various nuclear parameters that enter into the theoretical evaluation of experimental results. Such results come primarily from accurate measurement of the hyperfine interaction in which the electronic density at the nuclear position is used to probe the distribution of nuclear magnetization. Existing experimental results in the field are collected and discussed from the point of view of the single-particle model. (W.D.M.)
