TEMPERATURE OF LARGE CLUSTERS

Free clusters that cool by evaporation will have a defined distributio n of internal energies in spite of lack of contact with a heat bath. T his distribution has previously been considered for small clusters. He re we present results valid for large clusters. A simple Gaussian shap e is predicted in this regime and we calculate the mean and variance o f the distribution. The limit of validity of previous and present work is discussed. The analytical results are compared to numerical simula tions.
