Description

The hyperfine splitting of Mu in evacuated SiO2 powder has been measured over the temperature range 17-300 K using the two frequency method. Above 100 K it is consistent with the vacuum value (4463.3 MHz) indicating the Mu atom are moving freely between the particle grains. At lower temperatures it drops rapidly to 4437 +- 4 MHz at 17 K. The effect is attributed to thermal adsorption on the SiO2 surface. Measurements were also made on an Ar coated powder between 7-62 K. The hyperfine splitting is consistent with the vacuum value over this range. (Auth.)
