Cover Story: The presence of oscillatory structures in collisional cross-sections has been largely ascribed to quantum interference. However, oscillations in excitation and charge exchange cross sections have also been obtained from classical approaches. A decade ago, a collaboration reported good agreement between MOTRIMS and classical trajectory Monte Carlo angular-differential charge-exchange cross sections for collisions involving highly charged ions and alkali targets. Recently, such oscillations have also been reported for targets such as He and H2. In this work, the presence and origin of oscillations in the n-state-selective charge-exchange cross section are investigated in Ar16+ collisions with ground-state H atoms by means of the Z-CTMC method, an extension of the conventional CTMC approach.

Total, momentum-transfer, and differential cross sections, together with spin-polarization (Sherman) functions, are reported for elastic scattering of low-energy electrons from neutral strontium atoms over the energy range 0.001–15 eV. The calc...

We study exotic orbits in the photoassociation process by considering both the vibrational and rotational motions in a classical model. In the presence of rotational motion, the exotic orbits possess regular bound segments even when the total energy...

In this work, state-selective electron-capture processes in collisions of Ar16+ with ground-state hydrogen are analyzed in classical terms by means of the classical trajectory Z-CTMC method. Oscillations in the n-state-selective charge-exchange cross...
