    "abstract": "Using approximate partition functions and a master equation approach, we\ninvestigate the statistical relaxation toward equilibrium in selected CaAr$_n$\nclusters. The Gaussian theory of absorption (previous article) is employed to\ncalculate the average photoabsorption intensity associated with the 4s^2-\u003e\n4s^14p^1 transition of calcium as a function of time during relaxation. In\nCaAr_6 and CaAr_10 simple relaxation is observed with a single time scale.\nCaAr_13 exhibits much slower dynamics and the relaxation occurs over two\ndistinct time scales. CaAr_37 shows much slower relaxation with multiple\ntransients, reminiscent of glassy behavior due to competition between different\nlow-energy structures. We interpret these results in terms of the underlying\npotential energy surfaces for these clusters.",
