Abstract: The semiclassical limit, as the Planck constant $ \hbar$ tends to 0, of bound states of a quantum particle in a one-dimensional potential well is considered. The semiclassical asymptotic formulas for eigenfunctions are justified, and the Bohr-Sommerfeld quantization condition is recovered.
