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 4He and 0.3-0.9 GeV for 6Li for the deuteron photodisintegration kinematics ( theta Pcm=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.
