Nuclear partition functions
(Last update: 01/01/2009)
$G(Z,A) = \frac{1}{2J_0+1} \sum_\mu (2J_\mu +1) \exp(-E_\mu/kT)$
$G(Z,A) \approx \frac{1}{2J_0+1} \int \sum_J (2J +1) \rho(E,J)\exp(-E/kT) dE$
where $J_o$ is the ground state spin
The partition functions are calculated using experimental excited spectrum whenever available (RIPL-3 database) and if not, on the basis of the nuclear level densities obtained within the HFB plus combinatorial method (Goriely et al., 2008, Phys. Rev. C78, 064307)
