Preliminary data for Pd-107. 2314000100026
FACILITY (SYNCH,2JPNJAE) Exp.apparatus "Accurate Neutron-Nucleus2314000100027
Reaction measurement Instrument (ANNRI)" in Material 2314000100028
and Life science exp. Facility (MLF) at the Japan 2314000100029
Proton Accelerator Research Complex (J-PARC). 2314000100030
Beam line No 4 - BL04. 2314000100031
37.5 mm Pb filter was placed to suppress the gamma 2314000100032
flash. 2314000100033
Beam size was collimated to 3 mm diameter at the 2314000100034
sample position with a rotary collimator. 2314000100035
INC-SOURCE (SPALL) 2314000100036
DETECTOR (D4PI,GE,BGO) 4Pi Ge spectrometer: two cluster-Ge 2314000100037
detectors and BGO compton suppression detectors. 2314000100038
METHOD (TOF) TOF spectra of Pd - 105, 106, 107, 108 were 2314000100039
measured. 2314000100040
SAMPLE Pd-107 sample was supplied by the Nuclear Research and 2314000100041
consultancy Group (NRG), Netherlands; was reanalyzed in2314000100042
detail by a mass spectroscopy at the Kyoto University 2314000100043
Research Reactor Institute. 2314000100044
Pd-107 sample - pellet of 137.37 mg weight, 4.523 mm 2314000100045
diameter, 0.917 mm thickness; was packed in an Al 2314000100046
container of 229.76 mg weight, 9.077 mm diameter, 2314000100047
1.86 mm thickness. 2314000100048
Another Al container - for background. 2314000100049
Pd samples were set at the position of 21.5m from the 2314000100050
MLF neutron source with a 120-kW power (25 Hz). 2314000100051
PART-DET (G) Gamma-rays from neutron capture. 2314000100052
CORRECTION For dead time - correction factor was obtained by using2314000100053
the random pulse generator. 2314000100054
For self-shielding and multi-scattering effects by 2314000100055
the Monte Carlo simulation code MCNP. 2314000100056
MONITOR 1(5-B-10(N,A)3-LI-7,,SIG) 2314000100057
The TOF spectrum corresponding to the flux of neutrons 2314000100058
was derived by gating on the 478-keV gamma ray emitted 2314000100059
through the 10B(n, a g)7Li reaction. 2314000100060
2(5-B-10(N,G)5-B-11,,SIG) 2314000100061
Neutron flux was deduced from the gated TOF spectrum 2314000100062
and the neuron-capture cross sections of B-10 in 2314000100063
