Properties of some exotic five-particle systems

The stability of a number of exotic systems consisting of N=5 unit charge particles is investigated using the stochastic variational method. Several interesting exotic molecules are found to be stable. The properties of the most intriguing systems consisting of two electrons and two positrons (e.g.,...

Description
Summary:The stability of a number of exotic systems consisting of N=5 unit charge particles is investigated using the stochastic variational method. Several interesting exotic molecules are found to be stable. The properties of the most intriguing systems consisting of two electrons and two positrons (e.g., e{sup +}PsH or Li{sup +}Ps{sub 2}) are investigated in great detail.
