Abstract
Group-theoretical schemes of classification of the doubly excited states of the two-electron atom are based on the theory of addition of four angular momenta. A new scheme of classification of states with high total orbital momentum is proposed for the case when one electron is excited much more than another. The group-theoretical state vectors are compared with the results of the qualitative and numerical study of configuration interaction. Exceptions to the proposed classification scheme are discussed.Keywords
