Abstract
Exposure of frozen aqueous acids and alcohols containing Cd2+ salts to γ-rays at low temperatures results in the formation of a species which has the properties expected for Cd+. When the matrices are annealed, this reacts with excess Cd2 to from the diatomic Cd2 3+. In environments containing excess of Ag+ ions the analogous species [Ag–Cd]2+ is formed when the matrix is warmed.
