INC-SOURCE (A-BE) Neutrons in the energy range 6.3 to 8.3 MeV 2201200100010
were produced via the Be-9(alpha,n) reaction, using 2201200100011
1.86 to 2.76 MeV 200 uAmp alpha beams upon 0.52 um 2201200100012
thick Be-layers on high-pressure water-cooled copper 2201200100013
backings. 2201200100014
INC-SPECT Two monoenergetic neutron groups were present, but 2201200100015
the lower were always below the thresholds of the 2201200100016
reactions studied. 2201200100017
SAMPLE Pure Al samples with 36 mm diameter and 20 mm 2201200100018
thickness. 2201200100019
METHOD (ACTIV) For the short-lived Na-24-m product, a cyclic 2201200100020
milli-second pulsed irradiation-activity measurement 2201200100021
technique was utilized. 2201200100022
DETECTOR (GELI) A 40 cm3 Ge-Li detector were used for 2201200100023
activity measurements. 2201200100024
(SCIN ) A 5 cm diameter by 5 cm thick NE213 liquid 2201200100025
scintillator with n-gamma discrimination, 2201200100026
positioned at 90 degrees with respect to the neutron 2201200100027
beam direction, was used for neutron flux 2201200100028
measurements. The efficiency of this detector, 2201200100029
with a threshold of 2.9 MeV, was determined to 2201200100030
be 16.5% in the enrgy region considered. 2201200100031
CORRECTION Corrections were applied for neutron attenuation 2201200100032
and gamma self-absorption in the samples. 2201200100033
ERR-ANALYS (ERR-T) Total errors, composed of systematic and 2201200100034
statistical errors. 2201200100035
(ERR-1) -error in detector efficiency 6% 2201200100036
(ERR-2) -error in discriminator level 5% 2201200100037
(ERR-3) -error in attenuation correction 3% 2201200100038
(ERR-4) -geometry 2% 2201200100039
(ERR-5) -conversion of flux from 90 to 0 deg. 5% 2201200100040
