摘要：

(gamma, 2e) triple differential cross sections are presented for helium at 60 eV above the photodouble ionization threshold with energy-sharing ratios (R = E-2/E-1) for the two ejected electrons of R = 1, 5 and 11. The measurements were taken using a toroidal spectrometer and linearly polarized light from an undulator beamline (SU6) at the Super-ACO storage ring. Good agreement is found with TDCSs obtained by the CCC method and by the length gauge of 3C theory.
