Abstract : The Oppenheimer Brinkman Kramers theory of the capture of electrons by alpha particles in their passage through matter is formulated in terms of a momentum representation of the electrons. For a heavy ion carrying a core of electrons. capture is largely into excited states. Total cross sections for such ions are estimated assuming hydrogen like representations for the electron in the captured states and treating the atom from which capture takes place by the Thomas Fermi model.
