• T}ae quantum tunneling rate of a macroscopic particle in one-dimensional potentials subjectto oscillating external fields is considered using the complex time path integral rnethod and thetinae-dependent Schr6dinger equation. A simple caJctmIation scheme ['or obtaining the tttnnelingrate within quasi-classical accuracy is described and applied to two systems. The one is thetunneling rnotion through an inverted parabola potential and the other is the escaping motionfrorn a cubic potential well. Both systems are subject to srnall oscillating fields. It is foundthat both of the rates are exponentially enhanced due to the imaginary time rnotion of' thetunneling particle under oscillating potential barriers, and that time scale is identical to theBiittiker-Landauer traversal time.
