Endohedrally confined helium: Study of mirror collapses
The properties of a helium atom confined inside an endohedral cavity, such as a fullerene, are studied. The fullerene cavity is modeled by a potential well and the strength of this potential is varied in order to understand the collapse of different atomic wave functions into the fullerene cage. Thr...

The properties of a helium atom confined inside an endohedral cavity, such as a fullerene, are studied.
