M054000100004 AUTHOR (B.S.Dolbilkin,A.I.Isakov,V.I.Korin,L.E.Lazareva, M054000100005 N.V.Linkova,B.A.Tulupov) M054000100006 INSTITUTE (4RUSLEB) M054000100007 REFERENCE (J,YF,9,675,1969) M054000100008 (J,SNP,9,391,1969) - Eng.trans.of YF,9,675,1969 M054000100009 INC-SOURCE (BRST) M054000100010 FACILITY (SYNCH,4RUSLEB) M054000100011 SAMPLE Natural mixture ferrum sample, 90 g/cm**2. M054000100012 METHOD (EXTB) M054000100013 DETECTOR (BPAIR) Nine-channel magnetic pair spectrometer. M054000100014 ANALYSIS Photoabsorption cross section was obtained by M054000100015 subtraction of the atomic absorption cross section M054000100016 from the measured sum of atomic and nuclear M054000100017 absorption cross sections. M054000100018 REL-REF (R,,K.Siegbahn,B,SIEGBAHN,,1955) Atomic absorption M054000100019 cross section. M054000100020 ERR-ANALYS (DATA-ERR) Root-mean-squared errors are given. No M054000100021 information on -data-err and +data-err values for M054000100022 integrated cross section data. M054000100023 COMMENT The total nuclear cross section of gamma-quanta M054000100024 absorption in Fe in the energy region 10 - 26.5 MeV M054000100025 was measured by the absorption method. The M054000100026 measurements were performed with the bremsstrahlung M054000100027 spectrum of gamma-emission (Eg-max=260 MeV) on the M054000100028 Pian synchrotron. Photons were detected by a M054000100029 nine-channel magnetic pair spectrometer with the M054000100030 resolution about 1%. The integral cross section at M054000100031 10 - 26.5 MeV was found to be 735 +12 -50 mb*MeV. M054000100032 The integral cross section at 10 - 26.5 MeV is equal M054000100033 to 735 (-50,+120) and exhausts about 65% of M054000100034 classical dipole sum rule value.
