Se. Jones et al., EVALUATION OF MUON ALPHA-STICKING FROM LIQUID, NON-EQUILIBRATED D-T TARGETS WITH HIGH TRITIUM FRACTIONS, Hyperfine interactions, 82(1-4), 1993, pp. 303-311
In the past, evaluations of the alpha-muon sticking parameter in muon-
catalyzed d-t fusion (omega(s)) have generally been performed for low
tritium fractions C(t), where ddmu fusion significantly competes with
dtmu formation in the catalysis cycle. Here we use the approach of det
ermining omega(s) from high-C(t) data, that is, in deuterium-tritium m
ixtures with C(t) greater-than-or-equal-to 70%. We employed liquid deu
terium-tritium targets with low DT admixture to minimize corrections.
We will show that this approach results in considerable simplification
in the extraction of the sticking parameter. Data were taken at LAMPF
during the summers of 1989 and 1990. The value we obtain agrees well
with our earlier values and the latest value from PSI, yet remains sig
nificantly smaller than theoretical predictions.
