Abstract
The relativistic quantum electrodynamics is rigorously applied to calculate the cross section for photoelectric absorption of a Dirac electron in the field of a nucleus (of charge Ze). The case of quantum energies greater than the proper energy of the electron is considered. The total photo-absorption from the -shell is found in this way to be approximately where , as , and . The factor depending on is seen to modify the result appreciably for heavy elements, so that for lead, and the gamma-rays from Th C", (, X.U.), . The agreement with experiment is satisfactory.
