Monopole Coulomb-deflection factor for heavy-particle inner-shell-ionization cross sections

The repulsion between positively charged projectiles and the nucleus of target atoms gives rise to a Coulomb-deflection factor that reduces the inner-shell-ionization cross sections calculated for straight-line particle trajectories. In the monopole approximation to the repulsion, this factor depends on the function G/sub 0/(x) = (x dK/sub i/x(y)/dyVertical Bar/sub y/ = x)/sup 2/, where K/sub i/x is the Bessel function of imaginary order. Through identities between Bessel functions of complex order and argument we have, in this addendum to an earlier paper (W. Brandt and G. Lapicki, Phys. Rev. A 20, 465 (1979)), reduced the evaluation of G/sub 0/(x) to computed functions. Values of G/sub 0/(x) and its integrals as they appear in the theory of K- and L-shell ionizations are tabulated. The monopole approximation is compared with results based on the standard approximation G(x) = 1 which describes the experimental data.
