FACILITY (MICRT,2SWDLND)The experiment was performed at the L014900100015
tagged-photon facility located at MAX-lab in Lund, L014900100016
Sweden. L014900100017
SAMPLE Gaseous 3He cell located in a stainless steel block L014900100018
with dimensions 70 x 70 x 100mm3 served as the L014900100019
target.The beam entrance and exit windows were 12.5 L014900100020
mu-m thick.The cell was filled with 99.96% pure 3He L014900100021
gas to a nominal pressure of 2 bar. L014900100022
DETECTOR (TELES,SIBAR,SIBAR,SIBAR)Charged particles detected L014900100023
by four telescopes. Each telescope consisted of 3 L014900100024
detectors in dE-dE-E configuration. dE1 detector was L014900100025
25 and 50 mu-m thick, dE2 was 150 mu-m thick and E L014900100026
detector had thickness of 1000 mu-m. L014900100027
INC-SOURCE (BRST,TAGD) A 0.1% radiation-length Al radiator was L014900100028
used to generate a bremsstrahlung photon beam from L014900100029
the electron beam.Post-bremsstrahlung electrons were L014900100030
momentum analyzed using a magnetic spectrometer L014900100031
equipped with a 64-counter focal-plane scintillator L014900100032
array. Tagged photon-energy range was 14-31 MeV and L014900100033
the nominal photon energy resolution was 270 keV. L014900100034
