Abstract: The variation perturbation scheme based on hydrodynamic analogy to Schrödinger equation is adopted and the perturbed wavefunction for He atom in the ground state in a small and time dependent harmonic electric field and the polarizabilities and 1 st resonance frequency are calculated. Comparisons between the calculated results and experimental ones are also given.

Key words: Hydrodynamic analogy to Schrödinger equation, variation perturbation scheme, ground state
