A correlation between the two ratios γ/χ(0) and |Jm|/TK in Kondo system

Using the approach based on molecular field calculations for S=12 resonant level model; a close relationship between the two ratios γ/χ(0) and |Jm|/TK is obtained. Where γ represents the electronic contribution in the specific heat, χ(0) is the susceptibility at zero temperature, Jm is the molecular field parameter and TK is the Kondo temperature.
