SAMPLE Powder sample of Sc(2)-O(3). 99.9% purity. 3059900100010
Compressed disk of diam. either 11 mm (at E(n)=14.61 3059900100011
and 16.76 MeV) or 20 mm was used. 3059900100012
FACILITY (CCW,3CPRAEP) 3059900100013
(VDG,3CPRAEP) 3059900100014
INC-SOURCE (D-T) Ti-T targets, about 0.5mg/cm2 for Cockcroft- 3059900100015
Walton, thickness of about 1.5 mg/cm2 for VDG. 3059900100016
METHOD (ACTIV) Recoil alpha particle method was used for the 3059900100017
Cockcroft Walton accelerator, to monitor neutron-flux. 3059900100018
DETECTOR (NAICR) 80 mm dia. and 80 mm long NaI(Tl) scintillator.3059900100019

COMMENT After considering the effect of the oxide layer at the 3059900100021
surface of T-Ti target ,the neutron energy was modified3059900100022
from 14.61 to 14.58 MeV. 3059900100023
In recent years more reasonable averaged distance from 3059900100024
center of target to the center of sample was used. All 3059900100025
earlier data were adjusted for those effects. 3059900100026

=== Compiler's note, 81/09/16, 3059900200007
The value of Al-27(n,a)Na-24 cross-sections at 16.76 3059900200008

*** Compiler's note, 90/10/11, 3059900200010
It is not clear whether the value of Al-27(n,a)Na-24 3059900200011
at 16.76 MeV was used as monitor or not;moreover this 3059900200012
point is not reported in the new data set in 30523002 3059900200013
and 30523003 which are monitor-references. Therefore 3059900200014
compiler decided to remove this point from data set as3059900200015
monitor 3059900200016
CORRECTION At neutron energies of 14.61 and 16.76 MeV, 3059900200017
self-absorption of gamma-rays and at other energies, 3059900200018
neutron beam divergence, scattering of neutrons and 3059900200019
correction of sample thickness were considered. 3059900200020
