Comparative study of the d( gamma ,pn), 6Li( gamma ,pn)X and 4He( gamma ,pn)X processes by linear polarized photons in the energy range 0.3-0.9 GeV

The first results on photon asymmetry SIGMA for the process A(gamma, pn)X are presented for the energy ranges 0.45-0.55 GeV for He-4 and 0.3-0.9 GeV for Li-6 for the deuteron photodisintegration kinematics (theta-P(cm) = 90-degrees). The data on these nuclei are qualitatively similar to those for the deuteron, obtained in the same experiment, although a small but systematic difference may be observed in the energy range 0.3-0.6 GeV.
