Electromagnetic radiation in the general theory of relativity

Spaces allowing a normal, shear-free, expanding congruence of isotropic geodesics are considered. A metric form allowing the simultaneous solution of the Einstein and Maxwell solutions for an isotropic electromagnetic field is derived in explicit form.Some of the nomenclature and definitions encountered in this paper were specified in Part I [1].Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 5, pp. 32–35, May, 1973.
