摘要翻译:
在半经典近似下,用不稳定复轨道描述了一些隧穿现象。我们开发了一个系统的程序来稳定弹道和计算隧道概率,包括抑制指数和前置因子。我们发现,与稳定解相比,隧道解的不稳定性改变了前因子对h的幂律依赖性。

英文摘要:
Some tunneling phenomena are described, in the semiclassical approximation, by unstable complex trajectories. We develop a systematic procedure to stabilize the trajectories and to calculate the tunneling probability, including both the suppression exponent and prefactor. We find that the instability of tunneling solutions modifies the power-law dependence of the prefactor on h as compared to the case of stable solutions.
