- W2024351531 abstract "The second-order Oppenheimer-Brinkman-Kramers approximation is used to obtain a simple analytical formula, evaluated to the lowest order in the fine structure constant α in the numerator, for the differential cross section for electron capture to the continuum (ECC) by incident bare ions having velocity v from target hydrogenic atomic systems. Both non-relativistic and relativistic forms are derived. Comparison of the theory with the experimental data of Dahl (1985) and Andersen et al (1986) for H+, He 2+ + He collisions is reasonably satisfactory for energies > 50 keV/amu. However, theory shows that although the velocity dependence obtained by Andersen et al is v−11.3±0.2 in the range of impact energies 1–2.6 MeV/amu, this does not mean that the asymptotic v−11 velocity dependence given by the non-relativistic second-order OBK cross section is nearly attained. In fact it is shown that this cannot happen until an energy > 500 MeV/amu is reached where the effect of relativity produces a significant change in the energy fall off. Also a modification of the second-order OBK approximation obtained by Shakeshaft and Spruch (1978) has been expanded to first order in the atomic number ZP of the projectile ion to get simple formulas for the yield of continuum electrons and the cusp asymmetry factor β. The accordance with the data of Andersen et al (1986) is fair at energies > 0.5 MeV/amu/ZP but the situation is uncertain at lower energies since there is disagreement between different experimental groups and CDW theory results in smaller values of β than the OBK2 theory." @default.
