Abstract
Some of the Q0 and E¯ r factors from the 2003 to
2012 recommended k0-datasets were adopted from older literature
(Lit; before 1984), at the time of the launch of the k0-
method and have associated uncertainties of 10 %. The E¯ r
factors on the other hand, were derived analytically in 1979 and
1987 byemploying the Breit–Wigner resonance representation,
but in 1984 a multi-channel method was proposed for simultaneous
Q0 andE¯ r experimental determination. In this work we
assumed the a-dependence of theE¯ r parameter proposed later in
1987 for a generalization of this method, which was then
employed in the experimental determination of Q0 andE¯ r factors
for 17 (n,c) target isotopes on up to three channels of the
BR1 reactor at the SCK-CEN(Mol, Belgium).Retrospectively,
this ‘‘a-vectormethod’’ can be employed for a-calibration and it
provides a practical way of averaging the experimentalQ0 (and
E¯
r) results from several laboratories.OurQ0 results have 2–3 %
uncertainty and are compared with the Lit elsewhere.
