摘要：
The transition from the quantum tunneling regime to the classical crossover regime for a parameterized double-well potential is investigated. Using the different methods, the critical value of the potential parameter at which the first-order transition occurs is obtained. (C) 2001 Elsevier Science B.V. All rights reserved.
