On the extra factor 12√π in the Kramers approximation
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 √π2-are discussed. A quantum mechanical derivation of the Kramers approximation without the Gaussian approximation is given.
