M047700100004 AUTHOR (N.M.O'Fallon,L.J.Koester Jr,J.H.Smith) M047700100005 REFERENCE (J,PR/C,5,1926,1972) M047700100006 INSTITUTE (1USAUI) M047700100007 FACILITY (LINAC,1USAUI) M047700100008 INC-SOURCE (BRST) M047700100009 METHOD (COINC,EDE) M047700100010 DETECTOR (SOLST,SCIN) M047700100011 SAMPLE Low-temperature (4.20 (0.04) degrees K) He-3 gas with M047700100012 a pressure of 650 mm hg. M047700100013 PART-DET (P) M047700100014 (D) M047700100015 ANALYSIS The cross section was determined from the reaction M047700100016 yield by assuming that for very small interval M047700100017 between two points Eg1 and Eg2 cross section may be M047700100018 assumed to be constant. M047700100019 ERR-ANALYS (ERR-S) Statistical errors. M047700100020 (ERR-SYS) Systematic errors are only estimated M047700100021 to be less than 7%. They are: M047700100022 (ERR-1) uncertainty in the monitor calibration 2.3%); M047700100023 (ERR-2) uncertainty in the number of nuclei in the M047700100024 target 2.5%); M047700100025 (ERR-3) error in the actual number of events (1.0%); M047700100026 (ERR-4) error for nuclear interactions of M047700100027 particles 1.5%); M047700100028 (ERR-5) error for finite energy resolution (1.0%); M047700100029 (ERR-6) error from a systematic error in particle M047700100030 energies (3.0%). M047700100031 (ERR-T,,7.0) The sum of all these errors is 11.3%. M047700100032 Their root mean square is 5.0% but the fair M047700100033 value to assign systematic errors is 7%. M047700100034 CORRECTION The corrections were made for: M047700100035 - events missing because they had occured too soon M047700100036 after another event (correction was amounted to; M047700100037 1.9% at the least affected angle and 7.6% at the M047700100038 most); M047700100039 - falling of effective deuteron mass outside the M047700100040 acceptance interval (correction of 1% was made). M047700100041 COMMENT The photodisintegration cross section of He-3 at M047700100042 photon energies from 40 to 150 MeV and proton M047700100043 laboratory angles from 30 to 135 degrees have been M047700100044 measured.
