Muonium desorption to vacuum from hot iridium surface

Slow muonium (Mu) emission from the surface of iridium (Ir) foil has been observed in vacuum above \sim1200\ K with a yield of 5(1)% Mu per incident muon stopped in the foil. The relative Mu signal was found t...

Electrical resistivities of PrBa₂Cu₄O₈ under high pressures up to 7GPa

PrBa₂Cu₄O₈(Pr124) does not exhibit superconductivity but its resistivity shows a metallic behavior below 170K. This behavior is a sharp contrast to the semiconducting one of PrBa₂Cu₃O₇(Pr123). In this work, we ha...

Redox reaction of μ⁻O in water determined by the chemical shift

The chemical shift ofμ ⁻O in water, ice and in aqueous hydrogen peroxide (H₂O₂) was examined using μ⁻O resonance. Two distinct signals are obtained in water and ice. Usingμ ⁺ resonance signal as a standard, the o...
