Abstract:

A simple model is considered to study the effects of finite size and internal structure in the tunnelling of bound two-body systems through a potential barrier. It is demonstrated that these effects are able to increase the tunnelling probability. Applications may include nuclear fusion, hydrogen atom and Cooper pair tunnelling.
