چکیده
|
We use the optimized trigonometric finite basis method to find energy eigenvalues and eigenfunctions of the time-independent schrödinger equation with high accuracy. we apply this method to the quartic anharmonic oscillator and the harmonic oscillator perturbed by a trigonometric anharmonic term as not exactly solvable cases and obtain the nearly exact solutions.
