The rate coefficients for the de-excitation of the two lowest-lying excited levels of Ne (3s ^3P_2 and ^3P_1) have been investigated in the afterglow of a pulsed discharge in pure neon using absorption and fluorescence techniques. Thepressure dependences of the decay rates of the population densities of the two levels and the population density ratio of these levels at low electron and metastable densities yield the de-excitation rate coefficients for these levels by collision with neutral atoms, the diffusion coefficient for the ^3P_2 atoms and the effective transition probability of the imprisoned resonance radiation for the ^3P_1 atoms. In addition, from the decay rate of the ^3P_2 atoms in the early afterglow at appreciable electron and metastable densities, the de-excitation rate coefficients for this level by collisions with electrons and with other ^3P_2 atoms (metastable-metastable ionization) are deduced.
