Abstract

Negative muonium atom (μ + e e , Mu) has unique features stimulating potential interesting for several scientific fields. Since its discovery in late 1980’s in vacuum, it has been discussed that the production efficiency would be improved using a low-work function material. C12A7 was a well-known insulator as a constituent of alumina cement, but was recently confirmed to exhibit electric conductivity by electron doping. The C12A7 electride has relatively low-work function (2.9 eV). In this paper, the negative muonium production measurement with several materials including a C12A7 electride film will be presented.
