    "abstract": "An approximation method which combines the perturbation theory with the\nvariational calculation is constructed for quantum mechanical problems. Using\nthe anharmonic oscillator and the He atom as examples, we show that the present\nmethod provides an efficient scheme in estimating both the ground and the\nexcited states. We also discuss the limitations of the present method.",
