INC-SOURCE (BRST,KINDT) Peak energy of photon beam is 300 MeV. G005800100010
DETECTOR (TRD) Spark chamber telescope was used for proton G005800100011
registration. G005800100012
(SCIN) Plastic scintillator NE102A (30.5 cm length, G005800100013
17.8 cm diam.) was used for neutron registration. The G005800100014
angle between photon beam direction and neutron G005800100015
counter axis was 90+-0.5 degr in horizontal plane. G005800100016
SAMPLE 5.1 cm of liquid deuterium for deuteron G005800100017
photodisintegration was used. For O-16 G005800100018
photodisintegration cylindrical water target (5.7 cm G005800100019
length and 4.8 cm diam) was used. G005800100020
METHOD (COINC) Proton and neutron detected in coincidence. G005800100021
ADD-RES Differential cross section of O-16 photodisintegration G005800100022
was measured. Two angles for outgoing photoprotons G005800100023
were used. Horizontal angle beta (ANG) of outgoing G005800100024
protons was the angle between projection of outgoing G005800100025
proton momentum to horizontal plane and incident G005800100026
photon beam direction. This angle covered the range G005800100027
55<=ANG<=75 degr. Vertical angle alpha (ANG1) was the G005800100028
angle between projection of outgoing proton momentum G005800100029
to horizontal plane and momentum of outgoing proton. G005800100030
Differential cross section of O-16 photodisintegration G005800100031
was measured as a function of alpha angle (ANG1). G005800100032
Neutron detector was set at two positions G005800100033
(at 90+-0.5 degr to gamma-ray beam): G005800100034
1. Neutron counter in the horizontal plane G005800100035
