A. B. Migdal was born on March 11, 1911, in Lida (Belarus). In the 1920s his family moved to Leningrad. Migdal produced his first scientific work at age 17. He then enrolled at the physics department of the Leningrad State University (LSU), but studied there only a short while: arrested, he spent over two months under investigation, then was released (releases were still granted sometimes then). From 1931 to 1936, while working at the factory "Electrical Appliance," he produced several scientific works. At this time he managed to recover a place at the LSU extension division. After graduation in 1936 A. B. Migdal enrolled in graduate school at the Leningrad Physical-Technical Institute, where he formed his research interests and his own research style. His thesis adviser was M. P. Bronshtein. [Note: See footnote, p. 171.] Despite the briefness of this contact with Bronshtein – in 1937 Matvei Petrovich was arrested and executed – this bright, talented and deep person played a major role in Migdal's scientific development… Published in Vospominaniya ob Akademike A.

Various corrections to the single-particle model of electron magnetic scattering by odd nuclei are analyzed: core polarization, relativistic corrections, and the contribution of meson exchange currents. It is noted that use of a truncated basis in the description of core polarization grossly underestimates that effect and that upon transition to a complete basis core polarization becomes the main correction to the single-particle model. All the analyzed effects affect mainly the absolute magnitude of the form factors but leave practically unchanged the positions of the minima and maxima, which depend on the form of the single-particle wave function of the odd nucleon. This makes magnetic scattering an important test of self-consistent nuclear theories used in the calculation of the mean field that determines the form of these wave functions.

The Nolen-Schiffer anomaly and the double Coulomb differences, i.e., mass differences of mirror nuclei differing by two nucleons, are considered together. It is shown that in the calculation of these differences one must take into account a renormalization of the Coulomb amplitude because of the polarization of the core and also include the ''tail effect,'' i.e., the difference of the single-particle wave functions of the protons and neutrons. These two effects have been ignored in earlier work on this subject. It has turned out that the latter effect is particularly important, and its sign depends on the character of the density dependence of the amplitude GAMMA/sup xi/ responsible for pairing. The phenomenological non-Coulomb charge-dependent forces, the introduction of which permits elimination of the Nolen--Schiffer anomaly, make it possible to reproduce also the double Coulomb differences only if one assumes that the amplitude GAMMA/sup xi/ corresponds to the surface pairing.

It is shown that the isotopic and isomeric shifts of atomic and mesoatomic levels are determined to a considerable degree by spin-orbit forces.
