Figure 3

Ps-Kr scattering phase shifts for $L=0$, 1 and 2. For each partial wave, the lower curve (solid black) is for the static pseudopotential and the upper curve (dashed red) includes the effect of the van der Waals interaction with $C_6=152$ a.u. and $R_c=3.0$ a.u.

Figure 8

Ps-Ar scattering phase shifts. For each $L$, the lower curve (solid black) was calculated using the static-field pseudopotential, while the upper (dashed red) also includes the effect of the van der Waals interaction with $C_6=104.52$ a.u. and $R_c=3.0$ a.u.
