Symmetric resonant charge transfer in H/sup +/+H and He/sup 2+/+He collisions at extremely low energies
Journal Article

· Phys. Rev. A; (United States)
Symmetric resonant charge transfer (RCT) in H/sup +/+H and He/sup 2+/+He collisions has been investigated in the ultralow-collision-energy range 10/sup -3/--10/sup -7/ eV. The RCT cross section has been computed by partial-wave expansion in the molecular-orbital expansion method within the fully quantum-mechanical formalism. The calculated RCT cross sections become constant below Eapprox. =10/sup -6/ eV, corresponding to a scattering length of --6a/sub 0/ and --2a/sub 0/ for H/sub 2/ /sup +/ and He/sub 2/ /sup 2+/, respectively.
