  We have measured Ce 4f spectral weights of extremely $\alpha$-like
Ce-transition metal intermetallic compounds CeRh$_x$ (x=2,3) and CeNi$_x$
(x=2,5) by using the {\it bulk-sensitive} resonant photoemission technique at
the Ce $M_5$($3d_{5/2}\to4f$)-edge. Unprecedentedly high energy resolution and
longer escape depth of photoemitted electron at this photon energy enabled us
to distinguish the sharp Kondo resonance tails at the Fermi level, which can be
well described by the Gunnarsson-Sch\"onhammer(GS) calculation based on the
Anderson Impurity Hamiltonian. On the other hand, the itinerant 4f band
description shows big discrepancies, which implies that Ce 4f electrons retain
localized characters even in extremely $\alpha$-like compounds.
