  Quantum interference effects in inter-conversion between cold atoms and
diatomic molecules are analysed. Within the framework of Fano's theory,
continuum-bound anisotropic dressed state formalism of atom-molecule quantum
dynamics is presented. This formalism is applicable in photo- and
magneto-associative strong-coupling regimes. The significance of Fano effect in
ultracold atom-molecule transitions is discussed. Quantum effects at low energy
atom-molecule interface are important for exploring coherent phenomena in
hither-to unexplored parameter regimes.
