Abstract
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.
