Session J15 - Poster Session II.

A new method for calculating the hyperspherical adiabatic potential energy and its associated channel function of three-electron atoms has been developed. In this method, we first calculate channel functions at each hyperradius for a given set of partial waves of the three electrons using unsymmetrized basis functions constructed from the Discrete Variable Discretization (DVR) method. The couplings of the different sets of partial waves are then taken into account for a selected set of channels to obtain the adiabatic potential curves and the channel functions appropriate to the three-electron atom. The present method eases the burden of numerical treatment for higher angular momentum states. Some results will be presented and discussed.
