摘要
Several practical implications of the noncrossing property of one-dimensional Bohm trajectories are examined, It is shown that the position of a Bohm particle, the average transmission, reflection and dwell times, and thr probability distribution of these tunneling times, can all be obtained without actually calculating trajectories. On the other hand, the intuitive interpretation of the scattering of wave packers by potential barriers is discussed within the framework of Bohm's interpretation of quantum mechanics, In this regard, claims that Bohm`s approach lends to counterintuitive results art shown to be subjective.
