On the anomalous moderation of relaxation in an ultracold plasma

It is shown that the recent experiments wherein the ultracold plasma (Ne ∼ 2 x 109 cm-3; Te ∼ 0.1 K; Ti ∼ 10 μK) with anomalously high lifetime (∼ 100 μs) may be successfully explained on the basis of the earlier developed theory. The conclusions modelling plasma transition into metastable state and the electrons initial heating up to several Kelvin's degrees are presented. The earlier obtained expression for the metastable plasma recombination velocity is in agreement with the experimentally observed anomalously high lifetime. The conclusion is made that the new physical object the metastable overcooled plasma forecasted earlier is realized experimentally
