The evaluation of partition functions in the grand-canonical and canonical ensembles and the accuracy of the ensuing saddle-point approximations for the many-body energy level density are investigated. A simple method for obtaining the canonical partition function and average energy using the saddle-point approximation is also examined. Results are shown for the nucleus [sup 164]Er within an independent-particle model, where a comparison with the exact level density of the model is made.
