Variational Perturbation Method Based on the Principle of Moments
Variational Perturbation Method Based on the Principle of Moments is a scholarly work, published in 1968 in ''Physical Review''. The main subjects of the publication include ground state, wave function, physics, helium atom, helium, Variational method, perturbation theory, quantum mechanics, Non-Hermitian quantum mechanics, density functional theory, low-energy electron diffraction, resolvent, and perturbation. It is found that comparable results can be obtained by the present simple calculation.
