In the free electron model the spin-lattice relaxation time T_1^<(orb)> due to the interaction with the orbital motion of conduction electrons diverges if the nuclear Zeeman energy is neglected. Without neglecting it, T_1^<(orb)> with the field dependence of a form log(H_<ext>) is derived for high magnetic fields. The divergence which arises for H_<ext>=0 is removed by taking into account the dipole interaction between unclear spins. The effect of the electron correlation at high fields is examined by use of the RPA approximation. The Hubbard approximation for the exchange interaction has no effect. Therefore, by use of a reasonble approximation, the result that (T_1^<(orb)>)^<-1> increases in the presence of the exchange interaction is found. It is seen that the enhancement is small compared with the one for the spin paramagnetism.
