| We present results of our investigations on radiation trapping in sodium vapour excited to 3P level by weak laser pulses. The evolution of the fluorescence signal as well as the evolution of excited atoms distribution were studied using the Monte Carlo method. Some predictions of these investigations were checked experimentally. |
