Abstract

Emission of muonium (μ ⁺e^-) atoms from silica aerogel into vacuum was observed. Characteristics of muonium emission were established from silica aerogel samples with densities in the range from 29 mg cm^-3to 178 mg cm^-3. Spectra of muonium decay times correlated with distances from the aerogel surfaces, which are sensitive to the speed distributions, and follow general features expected from a diffusion process, while small deviations from a simple roomtemperature thermal diffusion model are identified. The parameters of the diffusion process are deduced from the observed yields.
