Three LiF targets with thickness L026000100017 of 300 and 600 mu-g/cm2 deposited on a 1.3 mu-g/cm2 L026000100018 mylar foil were used in experiment L026000100019 DETECTOR (SISD) Charged particles - alpha and tritons from Li L026000100020 photodesintegration were detected using Si array L026000100021 SIDAR in lamp-shade configuration, consisting of 6 L026000100022 upstram and 6 downstream Si strip detectors type YY1 L026000100023 of 300, 500, and 1000 mu-m thickness. Each detector L026000100024 is tilted at 42deg from the plane perpendicular to L026000100025 the beam axis. YY1 detectors are segmented into 5 mm L026000100026 wide annular strips and cover an active area with an L026000100027 inner radius of 5 cm and an outer radius of 13 cm. L026000100028 (HPGE) HPGe detector when placed at small angle to L026000100029 photon beam was used for detection of photons L026000100030 scattered from Cu sample. When placed in the L026000100031 attenuated beam it was used for photon energy L026000100032 measurement. L026000100033 METHOD (COINC) Coincidence between upstream and downstream L026000100034 array of SIDAR detectors detecting alphas and L026000100035 tritons, respectively (or vice-versa) was required L026000100036 MONITOR (79-AU-197(G,N)79-AU-196,,SIG) L026000100037 Reaction was used for absolute beam intensity L026000100038 determination using activation method at higher beam L026000100039 energies 9 and 10 MeV. L026000100040 MONIT-REF (K2342001,O.Itoh+,J,NST,48,834,2011) L026000100041 INC-SOURCE (LCS) The HIgS facility produces a quasimonoenergetic L026000100042 Compton backscattered photon beam tunable in wide L026000100043 energy range with either linear or circular L026000100044 polarization.The gamma-ray beams for this experiment L026000100045 were produced using the OK-5A helical wigglers.
