Abstract
THE photoelectric effect for -rays in heavy elements has not yet been treated satisfactorily, as it has always been found necessary to assume that Z/1371, where Z is the atomic number, or else that the wave function of the photoelectron could be replaced by that of a free electron. These approximations render the result rather uncertain, and, in view of the problem of nuclear absorption, it is very desirable to have some calculation of the photoelectric effect without any uncontrolled approximation.
