Contribution

It introduces analytical expressions for non-ideality parameters in ultracold plasmas, considering correlation and recombination heating effects.

Findings

Good agreement with experimental results

Conditions for creating strongly non-ideal electron subsystems

Analytical expressions for non-ideality parameters

Abstract

In the article an ultracold electron-ion plasma created by photoionization of cooled atoms is investigated. We obtained analitical expressions for non-ideality parameters which establish due to correlation heating. In the work the nearest neighbour and the Wigner-Seitz cell approximations were used, the recombination heating of electrons was taken into account. We have got a good agreement with the experiment results. The possibility of creation of strongly non-ideal electron subsystem has been shown and conditions of this process have been determined.
