Abstract
In previous papers [A. K. Bhatia, Phys. Rev. A 85, 052708 (2012); A. K. Bhatia, Phys. Rev. A 86, 032709 (2012); A. K. Bhatia, Phys. Rev. A 87, 042705 (2013)] electron-H, $\ensuremath{-}{\mathrm{He}}^{+}$, and $\ensuremath{-}{\mathrm{Li}}^{2+}$ $P$-wave scattering phase shifts were calculated using the variational polarized orbital theory. This method is now extended to the singlet and triplet $D$-wave scattering in the elastic region. The long-range correlations are included in the Schr\"odinger equation by using the method of polarized orbitals variationally. Phase shifts are compared to those obtained by other methods. The present calculation provides results which are rigorous lower bonds to the exact phase shifts. Using the presently calculated $D$-wave and previously calculated $S$-wave continuum functions, photoionization of singlet and triplet $P$ states of He and ${\mathrm{Li}}^{+}$ are also calculated, along with the radiative recombination rate coefficients at various electron temperatures.
