TITLE Thermal Neutron Capture Cross Section of Palladium-107 1413300100006
FACILITY (REAC,1USALAS) The experiments were performed using the1413300100007
internal target facility at the 8-MW Los Alamos Omega 1413300100008
West Reactor. 1413300100009
INC-SPECT The target was positioned at the center of the graphite1413300100010
thermal column about 1.5m from the edge of the reactor1413300100011
core, where the thermal neutron flux was about 6 x1E111413300100012
n/cm2, with a Maxwellian distribution corresponding to1413300100013
a temperature of 350 K. The Cd(In) ratio was about 1413300100014
2 x 1E3. 1413300100015
SAMPLE The Pd sample weighed 201.4 +/- 0.1 mg and its isotopic1413300100016
composition is 1413300100017

The largest chemical contaminant was 0.1% iron 1413300100025
DETECTOR (GE) The gamma rays emitted in the (nth,g) reaction 1413300100026
were measured with a 26-cm3 coaxial Ge(Li) detector 1413300100027
positioned inside a 20 cm-outer diameter x 30 cm-long 1413300100028
NaI(Tl) annulus. 1413300100029
METHOD (ACTIV) 1413300100030
MONITOR A 100.0 +/- 0.1 mg sample of (CH2)n was placed at the 1413300100031
target position together with the Zr sample in the 1413300100032
thermal column. All capture cross sections obtained in1413300100033
