摘要
The R matrix with pseudostates and convergent close-coupling methods are applied to the calculation of excitation and ionization cross sections for the simplified S-wave model of e-He+ scattering. Very good agreement is obtained between the results of the two methods. Furthermore, the problem of Rydberg series of pseudoresonances, converging to the unphysical positive-energy states in the continuum, is shown to be almost negligible if large basis sizes or simple averaging procedures are used.
