The dynamical spin-susceptibility of f-electrons in the Anderson lattice is theoretically studied in connection with neutron inelastic-scattering experiments in heavy fermion compounds. The dynamical susceptibility was calculated by using the theory of Anderson lattice formulated by Koyama and Tachiki. The functional form of १F"/(q,३)/३, १F"ptibility, is well approximated by a simple Lorentizian form, and its half width remains finite even for q 薔 0 and decreases with q. This result is consistent with the results of the neutron scattering experiments which observed the spin fluctuations of f-electrons in CeCu6.
