17. We define (formula presented) as the temperature at which (formula presented) reduces to 50% of its extrapolated zero-temperature limit. This definition of (formula presented) is common in dilute magnetic alloys, where (formula presented) corresponds to the electrical resistivity due to scattering off the magnetic impurities. With (formula presented) so defined, the half-width of the Abrikosov-Suhl resonance in the NCA impurity spectral function is about (formula presented)
