A theory is developed of the ionization of inner-shell electrons during ..beta.. decay. For allowed transitions it is shown that in the lowest order of the coupling constants the transition amplitude for the process is a sum of two terms, one of which attributes the ionization process to the sudden change in nuclear charge, and the other to a virtual scattering of an inner-shell electron by the emerging ..beta.. particle. For the K-shell-specific calculations are carried out using nonrelativistic hydrogenic wave functions and a Coulomb Green's function due to Glauber and Martin. Results whose relative accuracy is of order Z..cap alpha.. are obtained for energy spectra, angular correlation functions, and the total internal ionization probability; numerical results are presented for the nuclides /sup 63/Ni, /sup 107/Pd, and /sup 151/Sm. The role of the virtual-scattering mechanism is assessed and a comparison with other recent theoretical work is made.
