pl n. 1. (Nuclear Physics) slow neutrons that are approximately in thermal equilibrium with a moderator. They have a distribution of speeds similar to that of the molecules of a gas at the temperature of the moderator.Data concerning nuclear interactions are often given for standard thermal neutrons of speed 2200 metres per second, which is approximately the most probable speed at normal laboratory temperatures.1  Facebook.hey have a distribution of speeds similar to that of the molecules of a gas at the temperature of the moderator.
