Calculation of the magnetic susceptibility of a praseodymium Kondo system in the Anderson model

We have calculated the magnetic susceptibility of a praseodymium Kondo system in the Anderson model.This calculation explains correctly the negative conduction electron polarization found in the Kondo system La_1?xPr_xSn₃ and gives an evaluation of the parameter $\text{Гn(E}{}_{\mathrm{F}}\text{)}$ in satisfactory agreement with other determinations.
