摘要
将求解任意势中波函数与转移矩阵技巧相结合,给出计算穿越任意势之透射系数的一种简单数值计算方法.该方法被应用于抛物势和电场中的双垒势,计算所得透射系数与采用多阶势近似所得结果相符.还给出这两种情形在共振态时的波函数.
A simle numerical method of calculating transmission coefficients across arbitrary potentials is presented by using the combination of a transfer matrix procedure and the solution of the wave functions in arbitrary potentials.This method is applied to a parabolic potential and a double barrier potential in an electric field.The transmission coefficients calculated are in agreement with those obtained using a multistep potential approximation.The wave functions at the resonant states are also given for the two examples.
