Abstract
In this paper the nuclear energy level densities given by van Lier and Uhlenbeck, and by Bohr and Kalckar are compared with those given by Wergeland. It is shown that Wergeland's formula agrees slightly better with observational data. Wergeland's energy level density is then used to calculate the partition function of nuclei at a temperature of 1 Mev since this partition function enters into a discussion of the equilibrium theory of the origin of the chemical elements.
