Abstract
Standard arguments used to justify the adiabatic approximation in barrier penetration problems at extremely low bombarding energies are critically examined. A simple model calculation is used to illustrate how the relative strength of the coupling to the intrinsic degrees of freedom may affect the validity of the adiabatic approach.
