Excitation temperature

The Excitation Temperature ( $T_{\rm ex}$ ) is defined for a population of particles via the Boltzmann factor. It satisfies

where n_u and n_l represent the number of particles in an upper (e.g. excited) and lower (e.g. ground) state, and g_u and g_l their statistical weights respectively.
