@article{Ruiz2013HylleraasconfigurationinteractionAO, title={Hylleraas-configuration-interaction analysis of the low-lying states in the three-electron Li atom and Be + ion}, author={M. Ruiz and J. T. Margraf and A. M. Frolov}, journal={Physical Review A}, year={2013}, volume={88}, pages={012505} }
The total energies of 28 bound S, P , D, F , G, H ,a ndI states in the three-electron Li atom and Be + ion, respectively, are determined with the use of the configuration interaction (CI) with Slater orbitals and LS eigenfunctions and the Hylleraas-configuration-interaction (Hy-CI) methods. We discuss the construction and selection of the configurations in the wave functions, optimization of the orbital exponents, and advanced computational techniques. Finally, we have developed an effective… Expand
