Excitation of He/sup +/ by electron impact

Journal Article · · Phys. Rev., A; (United States)
A five-state close-coupling approximation in which 1s, 2s, and 2p eigenstates and 3s-bart-baru-barv-barw-barx-bary-barz-barI and 3p-barq-barr-bars-bart-baru-barv-barw-barx-bary-barz-barI pseudostates of He/sup +/ are included in the expansion, is used to calculate 1s ..-->.. 2s and 1s ..-->.. 2p excitation of He/sup +/ by electron impact in the intermediate energy range up to about three times ionization threshold energy. Pseudostates are chosen to maximize their overlap with bound states and low-lying continuum states of the same symmetry. Present results for 1s ..-->.. 2s excitation provide a link between accurate low- and high-energy results and agree with experiment above 70 eV. (AIP)
