26. A simplified notation of the three dipole allowed series of doubly excited P1 1o states is used, which originates in the first-order description of these states: (2snp+2pns), (2snp-2pns), and 2pnd states, respectively. The final states have D1 2e or S1 0e symmetry and they are singly excited so that the scattering path (neglecting interference) can be unambiguously referred to as na →ml, where m is the principal quantum number, a=±,0, and l=s,d.
