We report a high-energy magnetic-Compton-scattering study performed on the ferromagnet CeRh{sub 3}B{sub 2}. This technique solely measures the electron spin magnetic moments. In contrast to a number of Ce intermetallics with nonmagnetic elements, the Ce 5d spin moment is found to be large and parallel to the Ce 4f spin moment. Therefore the Kondo effect does not play a key role for CeRh{sub 3}B{sub 2}. The inferred large Ce 5d orbital magnetic moment is a signature of the strong spin-orbit interaction for the Ce 5d band. {copyright} {ital 1998} {ital The American Physical Society}
