Differential cross sections for electron capture from H-2(+) within the continuum-distorted-wave approximation

In the present work, the molecular continuum-distorted-wave approximation is formulated for the single-electron capture reaction from H-2(+) targets. The initial bound wave function is distorted by a projectile-electron continuum factor. In the exit channel, the final electronic wave function is distorted by a product of the continuum factors corresponding to the interaction between the electron and each one of the nuclei of the target. The doubly differential cross sections as a function of the projectile scattering angle are evaluated for different molecular alignments for the case of proton impact.
