Evidence for non Fermi liquid (NFL) behavior in Y{sub 1{minus}x}U{sub x}Pd{sub 3} and related systems is reviewed and discussed within the context of possible microscopic mechanisms. Low temperature electrical resistivity, specific heat, and magnetic susceptibility measurements on the Th{sub 1{minus}x}U{sub x}Pd{sub 2}Al{sub 3} system reveal unconventional Kondo behavior with NFL low temperature characteristics. Magnetic susceptibility measurements on UCu{sub 3.5}Pd{sub 1.5}, which has previously been shown to exhibit NFL behavior, are presented. Some systematics of the NFL low temperature behavior observed in several f-electron materials include a linear temperature dependence of the electrical resistivity {rho} {approximately} 1 {minus} aT with either positive or negative coefficient a, a logarithmically diverging specific heat C/T {approximately} {minus}lnT, and T{sup 1/2} asymptotic behavior of the magnetic susceptibility {Chi} {approximately} 1 {minus} T{sup 1/2}.
