The paranaagnon effect on the nuclear spin-lattice relaxation rate (7<=l/7".) isdiscussed by using the electron gas model for paramagnons conxbined wxth theDebye phoxxon model within the frantework of the strong-cotzpljng approxinva-tion. It is SIIOWII that the utaaxixtatm?at valtue of the ratio R5(T)/Rg (S and N standfor the stuperconducting and tlte nornaal states, respectively) is stmppressed by theparantagnon contribution which increases the life-time broadening of the quasi-particles.
