(W.M.Wilson,G.E.Thomas,H.E.Jackson) 1381900100005 TITLE Thermal neutron capture gamma rays from neutron capture1381900100006 in 59Ni and 63Ni. 1381900100007 FACILITY (REAC,1USAANL) Internal target facility at Argonne CP-51381900100008 reseach reactor. 1381900100009 INC-SOURCE (REAC) Reactor core. 1381900100010 INC-SPECT Reactor spectrum with cadmium ratio ~7. 1381900100011 SAMPLE Target consisted of approximately 2.1% 59Ni and 0.5% 1381900100012 63Ni as well as ~64.6% 58Ni, ~26.7% 60Ni, ~3.1% 62Ni, 1381900100013 ~1.9% 61Ni, and ~1.1% 64Ni; prepared for two months by1381900100014 irradiating 25 g of natural nickel in a high neutron 1381900100015 flux (1E15 n/sec) at the Oak Ridge high flux isotope 1381900100016 reactor (HFIR). 1381900100017 DECAY-DATA (28-NI-59,8.E+4YR) 1381900100018 (28-NI-63,1.E+2YR) 1381900100019 DETECTOR (GELI) Modified high resolution annihilation pair 1381900100020 spectrometer. 1381900100021 MONITOR (7-N-14(N,G)7-N-15,,SPC,,SPA) 1381900100022 Used as calibration standard for both relative 1381900100023 intensities and energies. 1381900100024 Relative intensities normalized to the 8999.3-keV 59Ni 1381900100025 ground state line, which intensity was arbitrarily set1381900100026 equal to 100. 1381900100027 ANALYSIS Each peak fitted with a reference line shape taken from1381900100028 the nickel spectrum. 1381900100029 ERR-ANALYS (E-ERR) Uncertainties in gamma-ray energies; function 1381900100030 of the errors in the energies of the nitrogen lines 1381900100031 and the errors in determining the centroids of the 1381900100032 nitrogen lines and the unknown line. 1381900100033 (DATA-ERR) Uncertainties of line intensities; mainly 1381900100034 statistical. 1381900100035 ADD-RES Obtained new values of the neutron binding energy for 1381900100036 the compound systems 59Ni, 60Ni, 61Ni, 62Ni, and 64Ni 1381900100037 as recoil-corrected gamma-ray energies of the ground 1381900100038 state transitions in each compound nucleus. 1381900100039 The gamma-ray spectra for neutron capture by 59Ni and 1381900100040 63Ni turned out to be not as strongly peaked at high 1381900100041 energies as the gamma-ray spectra observed for neutron1381900100042 capture by the even-mass target nuclei in the A~40-64 1381900100043 mass region. 1381900100044 HISTORY (20020128C) IS 1381900100045 ENDBIB 43 0 1381900100046 COMMON 1 3
