Distribution of a) energy and b) ejection angle of particles emitted from the grain. Data evaluated at the end of the simulation, 49.3 ps after ion-track formation. The curve in a) denotes a Maxwellian distribution, Eq. (2), with temperature T_fit = 1093 K fit to the data. The curve in b) represents a fit of the simulation data to Eq. (3) and describes the jet-like emission along the jet axis, ϑ = 0° and ϑ = 180°. c) shows the energy distribution at an earlier time, 21 ps; here the fit was performed with T_fit = 1946 K.
