2. Experimental

The experiments were carried out at the synchrotron radiation facility, BESSY, in Berlin using a 3m normal incidence monochromator (3m-NIM-1). The apparatus used for these experiments is described in an earlier publication (Gudipati 1995). The emission was passed through a 0.5 m monochromator (Acton Research) and detected with either a liquid N₂ cooled InGaAs photodiode equipped with a preamplifier (Electro-Optical Systems, spectral region 0.8 to 1.5 m) or a GaAs photomultiplier (Hamamatsu, R943-02; spectral region 0.18 to 0.9 m). Ar (99.999%) and CO (99.995%) from Linde were used for preparing the matrices. Matrix ration was typically 1:1000 (CO:Ar).
