Accuracy limits on the description of the lowest S excitation in the Li atom using explicitly correlated Gaussian basis functions

Stanke, Monika; Komasa, Jacek; Kedziera, Dariusz; Bubin, Sergiy; Adamowicz, Ludwik (2008)

We have performed very accurate quantum-mechanical calculations for the two lowest S states of the lithium atom in order to determine the transition energy. In the nonrelativistic part of the calculations performed ...
Explicitly correlated Gaussian calculations of the 2Po Rydberg spectrum of the lithium atom

Bubin, Sergiy; Adamowicz, Ludwik (2012)

Accurate quantum-mechanical nonrelativistic variational calculations are performed for the nine lowest members of the 2Po Rydberg series (1s2np1, n = 2, . . . , 10) of the lithium atom. The effect of the finite nuclear ...
Lower Rydberg 2D states of the lithium atom: Finite-nuclear-mass calculations with explicitly correlated Gaussian functions

Sharkey, Keeper L.; Bubin, Sergiy; Adamowicz, Ludwik (2011)

Very accurate variational nonrelativistic calculations are performed for the five lowest Rydberg 2D states (1s2nd1, n = 3, . . . ,7) of the lithium atom (7Li). The finite-nuclear-mass approach is employed and the ...
