Formation of (Xe2H)* centers in solid Xe via recombination: nonstationary luminescence and «internal electron emission»

Formation of (Xe2H)* centers in solid Xe via recombination: nonstationary luminescence and «internal electron emission»

The formation of excimers (Xe2H)* in solid Xe doped with molecular hydrogen under electron beam is studied using the original two-stage technique of nonstationary (NS) cathodoluminescence (CL) in combination with the current activation spectroscopy method — thermally stimulated exoelectron emission...
