The result of theoretical investigation of space-time track evolution created by heavy charged particles plasma in noble gases are presented. The model of track evolution taking into account the processes of electron and ion diffusion, electron energy relaxation due to collision, molecular ion formation, electron-ion recombination due to the ternary collision are considered. The electrical field formation and the charged particles drift under action of this field are took into account. The results of mathematical simulation of processes in track in helium are represented. The calculated results of ionization cross-section of helium atoms with fission fragments are compared with experimental data. 7 figs.
