    Figures & Tables(3)
    Profiles of (a) pressure, (b) electron temperature, and (c) density over the mass coordinate at various moments in time: 20 ps (curves 1), 100 ps (curves 2), 200 ps (curves 3), 500 ps (curves 4), 1 ns (curves 5), 1.5 ns (curves 6), and 2 ns (curves 7). These results were obtained from calculations for the impact of fast electrons with energy flux density Ih = 2 × 1017 W/cm2 and initial energy εh = 200 keV.
    Time dependences of the numerically calculated maximum values of pressure (curve 1) and density (curve 2), together with the pressure in the heated region according to the analytical expressions (3)–(6) under the impact of fast electrons with energy flux density Ih = 2 × 1017 W/cm2 and initial energy εh = 200 keV.
    Profiles of electron temperature (curve 1), density (curve 2), pressure (curve 3), and plasma emissivity (curve 4) at a moment in time 500 ps, which corresponds to the attainment of maximum density in the peripheral region of the shock wave. These data were obtained from calculations for the impact of fast electrons with energy flux density Ih = 2 × 1017 W/cm2 and initial energy εh = 200 keV. The short vertical line indicates the inner boundary of the heated region.
