SAMPLE Samples of natural titanium, chromium, iron, cobalt, 3097900100012
nickel and zinc, in the form of pure metallic or oxide 3097900100013
powder. 3097900100014
Al was in the form of aluminium oxide powder in order 3097900100015
to ensure uniform mixing with the sample powder. 3097900100016
FACILITY (CCW,3MORMOH) 3097900100017
INC-SOURCE (D-T) Neutrons were produced by bombarding a 0.6mg/ 3097900100018
cm**2 thick Ti-T layer with 150 and 300 keV deuterons, 3097900100019
the first ones originating from (D2)+ molecules in the 3097900100020
deuteron beam which were accellerated by the same high 3097900100021
voltage as the atomic D+. Neutron energy was selected 3097900100022
by the angular position of the sample with respect to 3097900100023
the deuteron beam axis. The calculated neutron-energy 3097900100024
scale was verified by measuring the energy dependence 3097900100025
of the Nb-93(n,2n)Nb-92-m and Zr-90(n,2n)Zr-89-m+g 3097900100026
cross sections. 3097900100027

ANALYSIS (DECAY) 3097900100030
CORRECTION Corrections have been made for self-absorption of 3097900100031
gamma rays in the sample and for gamma-gamma coin- 3097900100032
cidence summing effects. 3097900100033
ERR-ANALYS (ERR-T) Errors in the measured cross sections involve 3097900100034
uncertainties in: 3097900100035
(ERR-S,1.,4.) counting statistics (1 t0 4%), 3097900100036
(MONIT-ERR) monitor reaction cross sections(1%), 3097900100037
(ERR-1,1.,10.) corrections for gamma-ray 3097900100038
self absorption(1 t0 10%) 3097900100039
(ERR-2,1.,10.) coincidence summing effect (1 to 10%), 3097900100040
(ERR-3) sample chemical composition(0.1%), 3097900100041
(ERR-4,1.5,2.) Ge(Li) detector efficiency(1.5 to 2%) 3097900100042
(ERR-5) neutron flux time variation(0.1%). 3097900100043
Total uncertaianties in cross sections were obtained 3097900100044
by adding the uncertainty components in quadrature. 3097900100045
The total neutron energy spread was estimated taking 3097900100046
into account the kinetics of the neutron-producing 3097900100047
reaction, the deuteron energy loss in the Ti-T layer, 3097900100048
the D+/(D2)+ ratio as deduced from the angle dependence3097900100049
of the neutron energy, and the solid angle sustained 3097900100050
by the sample. 3097900100051
