[en] A compilation of nuclear charge- and magnetization-density-distribution parameters, found from elastic electron scattering, is presented. The data on charge distributions, obtained on the basis of a phenomenological model, are given in three separate tables: parameters of nuclei, differences therein between isotopes and between other neighboring nuclei such as isotones. A fourth table is devoted to charge distributions obtained by model-independent analyses. In the final table the available data on magnetization-density distributions are listed. References through April 1974 have been covered. (U.S.)
