Abstract
By a meticulous six-state close-coupling calculation of positron-hydrogen scattering using the Harris-Nesbet algebraic method, we have been able to locate below the n=2 hydrogen threshold three resonances instead of just one as Mitroy and Stelbovics (1994) recently reported. These resonances might have been identified roughly by Wakid (1975) and by Seiler et al. (1971) in a calculation employing a smaller coupling scheme.Keywords
