M059100100009 FACILITY (LINAC,2FR SAC) 600 Mev Saclay linac (ALS). M059100100010 INC-SOURCE (BRST) M059100100011 METHOD (COINC,MAGFR) M059100100012 DETECTOR (TELES,SCIN) M059100100013 Deutrons/tritons were analyzed in the focal plane of M059100100014 the spectrometer using a ladder counter consisting M059100100015 of four 90 mm x 220 mm x 2 mm plastic scintillators M059100100016 in coincidence with a large 460 mm x 240 mm x 5 mm M059100100017 plastic detector. M059100100018 Protons were detected using telescope consisted of M059100100019 two 200 mm x 220 mm x 5 mm plastic scintillators. M059100100020 ANALYSIS To extract the good events, a st of conditions was M059100100021 imposed on the spectra: broad cuts on the M059100100022 spectrometer pulse-height histogram define the M059100100023 selected kind of particle (deuteron or triton); then M059100100024 the time interval histograms for true and random M059100100025 coincidences associated with these selected events M059100100026 were established. The number of good events was M059100100027 defined as the number of events in the peak of the M059100100028 true coincidence plot, corrected by the average M059100100029 number of random coincidences read in the delayed M059100100030 coincidence plot. M059100100031 CORRECTION The following effects were considered: M059100100032 - proton absorption in the copper absorber situated M059100100033 in front of telescope; this correction never M059100100034 exceeded 15 %; M059100100035 - counting losses due to the high counting rate in M059100100036 the telescope scintillators: they were estimated M059100100037 from the single rates for each run and corrections M059100100038 were made ranging from 2 - 8 %; M059100100039 - events originating in the target walls: the M059100100040 correction amounted to 1.5 % in the worst case.

M059100100042 COMMENT Differential cross sections for the reactions M059100100043 3He(g,p)d and 4He(g,p)t were measured at proton c.m. M059100100044 angles of 60 and 90 degree for proton energies M059100100045 ranging from 150 - 450 MeV with an average resolution M059100100046 of 8 MeV. Bremsstrahlung was used as a photon source; M059100100047 deutrons/tritons were analyzed in a magnetic M059100100048 spectrometer whereas coincident protons were detected M059100100049 in a plastic scintillator telescope. The experimental M059100100050 method includes a calibration by means of 1H(g,pi)p M059100100051 differential cross section measurement at 90 degree M059100100052 c.m. in the same photon energy range. the 3H and 4He M059100100053 two-body photodisintegration differential cross M059100100054 sections show a monotonically decreasing variation M059100100055 with photon energy. in addition, partial data on the M059100100056 differential cross section of the reaction M059100100057 4He(g,n)3He at 90 and 120 degree neutron c.m. angle M059100100058 are given M059100100059 HISTORY (19990330C) Data were compiled at the USA BNL NNDC by M059100100060 V.V.Varlamov.
