Double excitation of helium atoms by impact of protons and highly charged ions
The impact parameter version of the four body-symmetric Eikonal approximation (SE2) is introduced to study double excitation of dielectronic atoms by heavy ions at high impact energies. The total cross sections are calculated for double excitation to the 2p2 (1D) state and the sum of the 2p2 (1D) an...

The impact parameter version of the four body-symmetric Eikonal approximation (SE2) is introduced to study double excitation of dielectronic atoms by heavy ions at high impact energies. The total cross sections are calculated for double excitation to the 2p2 (1D) state and the sum of the 2p2 (1D) and 2s2p(1P) states of helium atoms by impact of protons, Cq+ (q = 4-6) and Fq+ (q = 7-9) ions.
