Photoionization of Atomic Ions and Related Recombination Processes

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.In the article an ultracold electron-ion plasma created by photoionization of cooled atoms is investigated.

Two-center dielectronic recombination and resonant photoionization

Alexander B Voitkiv, Bennaceur Najjari

We consider radiative recombination and photoionization in an atomic system, which consists of two subsystems $A$ and $B$ . These subsystems are well separated in space and it is supposed that $A$ has a lower ionization potential. In such a case photoionization of $A$ and recombination of an incident electron with ${A}^{+}$ can be strongly influenced, via two-center electron-electron correlations, by resonant electron dipole transitions induced in $B$ . A theoretical description of these two-center resonant dielectronic processes is presented.We consider radiative recombination and photoionization in an atomic system, which consists of two subsystems $A$ and $B$.
