Maximum momenta p_max for two numerical solutions (dots) and from analytical expressions (solid lines). The blue line is from Eq. (14) and the dots are from the numerical solution with uniform u₂ (dashed lines in Fig. 8). The orange line is calculated with Eq. (15) with x_p1 and x_p2 from (1) and the dots are from the numerical solution with x_B = 0.03R, u_AB = −2u₁ (solid lines on Fig. 8). The value of p_max is measured at the level where the distribution function drops below the power-law extrapolation in e times for the orange dots and in 10 times for the blue dots.
