A large number of neon atoms are in thermal equilibrium. What is the ratio of the number of atoms in a 58 state to the number in a 3p state at?
(a) 300 K;
(b) 600 K;
(c) 1200 K? The energies of these states are shown in Fig. 38.24a.
(d) At any of these temperatures, the rate at which a neon gas will spontaneously emit 632.8-nm radiation is quite low. Explain why.
