Query: Quantum scattering with semiclassical asymptotic motion   Conventional scattering theory is incomplete in that it does not adequately
describe the behaviour of the wave function at macroscopic distances from the
scattering reaction volume. In scattering experiments particles are incident
from sources at macroscopic distance and measured at macroscopic distance from
the microscopic reaction volume. Standard experimental procedure is to describe
asymptotic particle motion by classical mechanics. However, this transition to
classical mechanics is not accounted for in standard quantum scattering theory.
Hence, we revisit conventional scattering theory with the introduction of
semiclassical propagators to describe the wave function in both incident and
outgoing asymptotic scattering channels. This description leads to the
manifestation of classical trajectories in the quantum wave function both
before and after the collision. It includes the case of extraction with
external fields as in modern multi-particle detectors. We derive the asymptotic
Kemble imaging theorem (IT) limit to demonstrate how formal quantum scattering
theory contains implicit classical mechanics threaded throughout the asymptotic
wave functions.
