The zero-energy Born exchange amplitude for electron-helium scattering in the forward direction has been calculated using a multi-parameter Hylleraas-type wavefunction. Up to 125 terms are used and the result is extrapolated to be 3.9430+or-0.0016. The present calculation substantiates the conclusion reached in several recent papers that the zero-energy form of the Gerjuoy-Krall dispersion relation (1960, 1962) does not hold for e - -He scattering.

Effect of screened Coulomb (Yukawa) potentials on the doubly excited meta-stable bound states and the resonance states with unnatural parities of the helium atom have been investigated in the framework of stabilization method using CI-type basis functions. A total of 54 resonances (6 each of 1Do and 3Do states, 12 each of 1Fe and 3Fe states, 9 each of 1Go and 3Go states) below the He+(3P) thresholds have been estimated by calculating the density of resonance states using a stabilization method. The resonances belong to the different 3lnl′ (n ≥ 3) series. We have also calculated the doubly excited 1,3Fe and 1,3Go meta-stable bound states of He atom below the He+ (2P) thresholds. The resonance energies and widths along with the meta-stable bound states energies are reported for various screening parameters. In free atom case, some of the F-wave resonance states and most of the cases, F- and G-wave resonance widths are reported for the first time. © 2008 Wiley Periodicals, Inc. Int J Quantum Chem, 2008
