摘要：

A relativistic scattering calculation based on the Dirac R-matrix method has been performed within a two-electron model-potential approach for negative-ion binding energies as well as elastic and inelastic scattering cross sections. We find multiplets of narrow shape resonances with J = 0, 1, and 2, and widths of a few meV. Their J-averaged energies for even and odd parity are 119.0 meV below the 6p1/2 threshold and 9.1 meV above the 6s1/2 threshold.
