  A solvable molecular collision model that predicts Aharonov-Bohm (AB) like
scattering in the adiabatic approximation is introduced. For it, we propagate
coupled channel wave packets without resorting to a Born-Oppenheimer (BO)
approximation. In those, exact, solutions we find evidence of topological phase
dislocation lines that are independent of the collision energy and provide
definitive signatures of AB-like scattering. The results of these simulations
contrast with the conclusions of a recent study that suggests survival of the
molecular Aharonov-Bohm (MAB) effect only in the adiabatic limit in which the
nuclear reduced mass $\mu \rightarrow \infty$.
  We discuss generalizations of this model and consider possible screening of
the Mead-Truhlar vector potential by the presence of multiple conical
intersections (CI). We demonstrate that the Wilson loop phase integral has the
value $-1$ if it encloses an odd-number of CI's, and takes the value $+1$ for
an even number. Within the scope of this model, we investigate the ultra-cold
limit of scattering solutions in the presence of a conical intersection and
comment on the relevance of Wigner threshold behavior for s-wave scattering.
