Abstract: | Two exactly solvable models—the double oscillator model and the associated harmonic oscillator model for which the Kramers approximation taken in the Gaussian approximation has an extra factor -are discussed. A quantum mechanical derivation of the Kramers approximation without the Gaussian approximation is given. |
