Abstract
The hyperspherical method as we know now stems from the pioneering wor k of Macek on doubly excited states of helium [J. Macek, J. Phys. B 1 (1968) 831]. It played an important role in classifying doubly excited Rydberg series according to the radial normal modes [U. Fano, Phys, T oday 29 (1976) 32] of the two electrons. We review not only its applic ation to the classification of doubly excited states but its related t echnical innovations that have turned the method into one of the most reliable numerical schemes for handling scattering problems for three- body systems. We take a glance at its wide applications from the low-e nergy electron impact ionization of H through the fast proton/antiprot on impact excitation of He.
