Abstract Angular differential cross sections for elastic scattering and charge transfer in low-energy He$^+$-He collisions underpin diverse plasma applications, yet systematic quantum mechanical data remain scarce. Employing the fully quantum mechanical molecular-orbital close-coupling method with high-accuracy ab initio potential energy curves, absolute angular differential cross sections are computed over 0.005-1250 eV/u and scattering angles 0.01$^\circ$-90$^\circ$. The present results show good agreement with available high-resolution experimental benchmarks in both magnitude and oscillatory structure, with improved consistency over existing semiclassical and single-electron approaches. By decomposing the cross sections into separate symmetric and antisymmetric channel contributions, three classes of oscillatory structures and their energy evolution are identified: regular oscillations from two-channel quantum interference, irregular oscillations from rainbow scattering in the deep attractive well, and fine-scale oscillations from matter-wave diffraction off the repulsive wall. This work provides the first systematic, fully quantum mechanical differential cross-section dataset across the low-energy and full angular range, serving as reliable reference data for plasma modeling and related applications.

Online attention
Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
