FIG. 11: Paramagnetic susceptibility as a function of temperature of SmPd$_{2}$Al$_{3}$ calculated using CF model (see text). Calculated curves for the CF parameters from NdPd$_{2}$Al$_{3}$ (a) and for our first principles calculated CF parameters for SmPd$_{2}$Al$_{3}$ (b) and calculation the CF acting on the ground state multiplet J = 5/2 only (c). Experimental data are displayed in the bottom panel (d). 23
