    "abstract": "A variationally improved Sturmian approximation for solving time-independent\nSchr\\\"odinger equation is developed. This approximation is used to obtain the\nenergy levels of a quartic anharmonic oscillator, a quartic potential, and a\nGaussian potential. The results are compared with those of the perturbation\ntheory, the WKB approximation, and the accurate numerical values.",
