Abstract
Some doubly excited resonances in electron-hydrogen scattering converging on the N=6 hydrogen threshold are calculated by a method of complex-coordinate rotation. Hylleraas-type wavefunctions are used for L=0 and L=1 resonances, and products of Slater orbitals for states with L>or=2. Both states with parities (-1)L and (-1)(L+1) are calculated. Resonance parameters for states with 'supermultiplet' quantum number I=0 are reported. Present results indicate that the doubly excited H- atom exhibits characters similar to those of a linear XYX triatomic molecule.Keywords
