Symmetric Rotor of Hollow States — •Lars Bojer Madsen and Klaus Mølmer — Insitute of Physics and Astronomy, University of Aarhus, DK-8000, Aarhus C

A triply excited state in lithium, also referred to as hollow state, represents a fundamental case of highly correlated three-electron dynamics in a purely Coloumbic four-body system.

Based on the dynamical O(4) symmetry of the Coulomb problem, we present an analytical scheme for the explicit construction of highly correlated triply excited hollow states in Coulombic three- electron systems. The Ansatz for the three-electron state is physically well justified and it produces configuration- interaction mixing coefficients in qunatitative agreement with data obtained from ab initio calculations.
