A synchrotron radiation study of high-lying excited states of matrix-isolated atomic magnesium

A synchrotron radiation study of high-lying excited states of matrix-isolated atomic magnesium

Previous steady-state and time-resolved luminescence spectroscopy of 3p ¹P₁ atomic magnesium, isolated in thin film samples of the solid rare gases, has been extended to include the higher energy 4p ¹P₁ excitation. Well resolved site splittings have been recorded in Mg/Ar samples for excitation to t...
