Description

Surface muons produced in UT-MSL were introduced into argon gas of 4.0±0.2 atm with NO2 (0-30 ppm), and muonium signals were detected in the presence of a transverse (1.7-3.4 G) and a longitudinal magnetic field (0-3.5 kG) at 295±1 K. The cross section for the transverse relaxation was (11.0±1.0)x10-16 cm2. The relaxation rates in different longitudinal magnetic fields show that the rate does not follow the conventional equation which assumes that the relaxation occurs mainly by spin-exchange interaction. Similar measurements were performed for the Mu+O2 system. These findings indicate that chemical reactions contribute to these relaxation rates. (orig.)
