M045500100004 AUTHOR (A.Zieger,P.Grewer,B.Ziegler) M045500100005 REFERENCE (J,FBS,1,135,1986) M045500100006 INSTITUTE (2GERMPH) M045500100007 FACILITY (MICRT,2GERMNZ) Mainz-microtron MAMI. M045500100008 INC-SOURCE (KINDT,BRST) M045500100009 METHOD (MAGFR) The photoprotons are magnetically deflected M045500100010 out of the photon beam and focused onto a detector. M045500100011 SAMPLE The deuterated target consisted of a stack of two M045500100012 pieces of deuterated polyethylene foil, the total M045500100013 thickness of which was determined to be 9.76 (0.18) M045500100014 mg/cm**2. The components, given by percentages in M045500100015 weight, are: 75.54% for C-12, 23.73% for H-2, and M045500100016 0.73% for H-1. The concentrations for oxygen and M045500100017 nitrogen were found to be below 0.5%. M045500100018 PART-DET (P) M045500100019 DETECTOR (SOLST) The detector is circular, ruggedized, M045500100020 partially depleted surface-barrier detector with a M045500100021 sensitive area of 2000 mm**2 and a depletion depth M045500100022 of about 300 mu. This detector was cooled to about M045500100023 200 degrees k by the use of liquid nitrogen. M045500100024 ANALYSIS Using the same deuterated target, the same magnet M045500100025 system and the same detector, the yield of compton M045500100026 electrons was measured that were emitted into the M045500100027 same solid angle as the photoprotons. Since the M045500100028 compton cross section is well known, the rate of M045500100029 photoprotons in terms of the incident photon flux M045500100030 can be calculated accurately and is independent of M045500100031 the properties of the beam monitor and the shape of M045500100032 the bremsstrahlung if the spectrometer is set in M045500100033 both measurements to the same primary photon energy M045500100034 bin. M045500100035 ERR-ANALYS (ERR-S) Statistical error only. M045500100036 COMMENT The absolute differential cross section for the M045500100037 photodisintegration of the deuteron at 0-degrees for M045500100038 the outgoing proton has been measured at 10.74 MeV M045500100039 lab photon energy using bremsstrahlung beam, a M045500100040 deuterated target, a magnet system, and a M045500100041 surfacebarrier detector. The absolute cross section M045500100042 was determined with an angular distribution of 1.25 M045500100043 degrees. The result, pertaining to a 4.6 MeV wide M045500100044 photon energy interval, favours a minimum in the M045500100045 differential cross section around 10 MeV photon M045500100046 energy.
