摘要：

Interference effects in slow He2+ +H(1s) charge-exchange collisions are analyzed within the framework of the dynamical adiabatic theory of atomic collisions. Analytic continuation of the dynamical adiabatic scaled-energy eigenvalues into the complex plane of internuclear separation R for the HeH2+ system is used to identify relevant branch points responsible for both radial and rotational nonadiabatic transitions leading to the electron capture process. The calculated electron capture probabilities are compared with the results of hyperspherical close-coupling calculations.
