Abstract
Potential barriers in atomic interactions often lead to shape resonances in which atoms are held together by the barrier. The importance of these resonances in thermal atomic collision processes is assessed. Radiative association is discussed as an example, and numerical results for CH formation suggest that the presence of a potential barrier might enhance the association rate.Keywords
