in quantum mechanical systems. An interesting perspective on the role of interference in semiclassical and Bohmian contexts is to be found in a recent article by Zhao and Makri.[@zhao03]

Whereas paper I focused on stationary bound states for 1D systems, the present paper (paper II) and the next in the series (paper III)[@poirier05bohmIII] concern themselves with stationary scattering states. The CPWM decomposition of paper I is uniquely specified for any arbitrary 1D state—bound or scattering—and in the bound case, always satisfies the correspondence principle. However, the non-$L^2$ nature of the scattering states is such that the paper I decomposition generally does [*not*]{} satisfy the correspondence principle in this case. Simply put, the quantum trajectories and LMs exhibit oscillatory behavior in at least one asymptotic region (thereby manifesting reflection), whereas the semiclassical LMs do not. This is not a limitation of the CPWM, but is rather due to the fundamental failure of the basic WKB approximation to predict any reflection whatsoever for above-barrier energies, as has been previously well established.[@berry72; @froman; @heading] In semiclassical theory, a modification must therefore be made to the basic WKB approximation, in order to obtain meaningful scattering quantities. As discussed in Sec. \[scattering\] and in paper
