We have investigated theoretically the NMR Iongitudintal relaxation rate,T7,?, due to magnetic impurities diluted in a metal where conduction electronsare in the "isothermal limit," and the magnetic ion has a substantial crystal-fieldsplitting. The theory is applied to a singlet ground-state Pr-compound, and theresult reveals an anomalous behavior of T ' as a function of temperature. Thet,ytheory is also applied to the doublet ground-state Dy-compound (YAI.: Dy).The anomalies in T7J observed experimentally by Abe for YAI. : Dy can besuccessfully explained by the present theory, provided that the first excited stateof Dy' " is about 5 K from a T, doublet ground-state.This is the first theoretical investigation of the NMR broadening due to magnetictons in metals in which the magnetic ton has a crystal-field splitting and conduc-tion electrons are in the "isothermal limit."
