Query: On Scattering of 1-D Wave Packets   We present an exact solution to the one-dimensional (1-D)
scattering-from-a-barrier problem for an incident neutron described by a wave
packet. As an aid to presenting our approach, we spend some time on a basic
review of how wave packets appear in standard quantum mechanics (SQM), paying
attention to interpretive aspects of a working theory both familiar on the one
hand while historically subject to debates, confusion, and misunderstandings on
the other. Several appendices also are included to address various mathematical
issues that may be helpful to some readers.
