Abstract

A new survey of muonium states brings the total of binary non-magnetic oxides studied to 30, with normal muonium—the interstitiallytrapped atomic state—found in 15 of these. The number of shallow-donor states of the type known in ZnO now also totals 15, but thereare hints of several others. Tantaliz...
