Mean excitation energies of the nuclei 140Xe (upper lines) and 94Sr (lower lines) in thermal contact as a function of the total intrinsic excitation energy. For the full lines, the level densities are described by the constant-temperature formula over the whole energy range above the ground state. The temperature parameters of the two level densities are obtained from the empirical parametrization of Ref. [19]. The dashed lines denote the partition according to the mass ratio.Reuse & Permissions

Mean excitation energies of the nuclei 140Xe (upper lines) and 94Sr (lower lines) in thermal contact as a function of the total intrinsic excitation energy. The dotted lines are derived from the condition of equal temperatures. The full lines result from the condition of statistical equilibrium, considering all states of the two nuclei. The level densities are described by the composite Gilbert-Cameron formula. The arrows denote the matching energies. The dashed lines denote the partition according to the mass ratio.Reuse & Permissions
