Performance of the Effective-characteristic-polynomial Pi2 Method for Diatomic Molecules: Basis-set Dependencies and Vibrational Levels
The performance of the recently introduced $\Pi$2 method [1] is investigated for some diatomic molecules. For this end, ground state energies are calculated at the MP4 level for various basis sets of…
Power series expansion of the roots of a secular equation containing symbolic elements: Computer algebra and Moseley’s law
We use computer algebra to expand the Pekeris secular determinant for two-electron atoms symbolically, to produce an explicit polynomial in the energy parameter e, with coefficients that are…

TLDR
It is shown that these summation methods give good results for the quartic and sextic anharmonic oscillators, and, even in the case of the octic an Harmonic oscillator, which represents an extremely challenging summation problem, two-point Pad\'e approximants give relatively good results.
