Measurement of total $$gamma$$ absorption for high energy $$gamma$$ rays

Kitatani, Fumito  ; Harada, Hideo   ; Hara, Kaoru; Utsunomiya, Hiroaki*; Goko, Shinji*; Kaihori, Takeshi*; Toyokawa, Hiroyuki*

Total $$gamma$$ absorption cross sections are most important data used in various fields related to the application of $$gamma$$ rays. However, the measurements of the total $$gamma$$ absorption cross section were difficult for high energy $$gamma$$ rays since there were no suitable $$gamma$$ ray sources. Recently, the nuclear photo-absorption measurement system using the laser-Compton backscattering (LCS) $$gamma$$ rays and the high-resolution high-energy photon spectrometer (HHS) were developed. We have utilized the system to measure the total $$gamma$$ absorption cross section, that is, the sum of the atomic and nuclear interactions. The total $$gamma$$ absorption cross sections at 10 MeV for Al and Cu have been measured with the system. The preliminary results show that the obtained values agree fairly with the theoretical.
