Screening function universal

The universal screening function, (2.15), is shown in Fig. 2.2 along with several of the classical screening functions given in this section... 

Fig. 2.2. The reduced screening functions of (2.15). This screening function is identified as Xu, a universal screening function, with its argument, x, being defined as x = rlav, where av is the universal screening length given in (2.17) (Ziegler et al. 1985).

Fig. 5.2. The universal screening function, Fig. 2.3, can be used to calculate the nuclear stopping power using (5.13). The result is shown in reduced coordinates. Also shown are the nuclear stopping calculations based on the four classical atomic models (Ziegler et al.
