Quasi steady-state distributions for particles with power-law interaction potentials

“…Examples that display common features of the process under investigation and for the parameters that are rather far from those considered analytically are given. Considering the experimental situation on irradiation of a thin GaAs film by a fast ion beam [8], we provide a comparison of the results obtained in the experiment with those obtained by numerical simulation. Then we conduct the qualitative illustrative comparison of the NE electron distributions obtained numerically with those adapted from [7].…”

“…Some experimental data on the emission current from metals irradiated by lasers can be reasonably explained by the mechanism for the formation of NE distributions [4][5][6][7][8]. It was shown [3,6,8] that, for a semiconductor plasma in the energy range E −E F > E F (where E F is the Fermi energy) a power-like distribution with a non-zero flux of energy or particles in momentum space can be established. This NE distribution function is formed both due to collisions with electrons whose energy is in the range E−E F > E F and background (equilibrium) electrons.…”

“…The analytical consideration of the NE distribution function formation in the case of non-stationary, non-localized, mismatched on intensity sources and sinks is very problematic, thus numerical treatment must be used. For the numerical investigation of the problem, we develop the original conservative schemes whose efficiency is proved in different problems (see, for instance, [8,9]).…”

“…Asymptotic results are confirmed by numerical calculations with high accuracy and the comparison of the numerical calculations with the analytical asymptotic results, in turn, proves the high accuracy of the exploited difference schemes. On the basis of fulfilled study the satisfactory analysis of the concrete experimental situation [8] is performed and a qualitative comparison with results from [7] is given. Conclusive remarks are given in Sec.…”
