Problem 3. A certain atom has a doubly degenerate ground level pair and an upper level of four degenerate states at 450 cm-above the ground level. In an atomic beam study of the atoms it was observed that 30 per cent of the atoms were in the upper level, and the translational temperature of the beam was 300 K. Are the electronic states of the atoms in thermal equilibrium with the translational states?
