Convergent close-coupling calculations of electron scattering on HeH+



Barry I. Schneider


We use the molecular convergent close-coupling (MCCC) method to perform calculations of 10–1000 eV electron scattering on the ground state of HeH+. Cross sections are presented for excitation of the n = 2−3 singlet and triplet states (where n is the united-atoms-limit principle quantum number), as well as ionization.We also present cross sections for He+ and H+ ion production following dissociative excitation and ionization. The He+ production cross section is compared with the measurements of Lecointre, Jureta, Urbain, and Defrance [J. Lecointre, J. J. Jureta, X. Urbain, and P. Defrance, J. Phys. B At. Mol. Opt. Phys. 47, 015203 (2014)]. We find that the MCCC results are up to 30% higher than experiment.
