This paper presents a method of evaluation of frequency dependent optical scattering rate r(ω) and the effective mass mb m* (ω) of heavy electron compound CeAl3. Two plasmon frequency ωp (unrenormalised) and ω*p (renormalized) for some of the heavy compounds are also evaluated. Our theoretical results are in good agreement with the experimental data and other theoretical workers.
