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.

description 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. Three theoretical calculation methods have been developed: a relaxation method, a Sturmian basis method, and a variational method. The first two methods are nonperturbative. The three methods allow inclusion of full correlations among the two electrons.
