We have undertaken a first-principles theoretical study of the Anderso
n hybridization in cubic CeCd and CeAg as a function of volume reducti
on. We present results for the hybridization width DELTA (epsilon) in
both the J = 5/2 multiplet and in the GAMMA8, GAMMA7 Crystal field sta
tes of the f1 Ce configuration. We also calculate the hybridization co
ntribution to the magnetic transition temperature. This is found to in
crease with pressure but is smaller than the experimental values, indi
cating that the Coulomb exchange contribution to the magnetic coupling
is not negligible in these compounds.
