Abstract We investigate the effect of pair-breaking on the contribution of s-wave order parameter fluctuations to the NMR relaxation rate for clean 2D superconductors. For Gaussian fluctuations we evaluate the Maki-Thomson diagram taking into account pairing breaking in both the fluctuation propagator and the Green's functions. The fluctuation peak in 1/T 1 near Tc is strongly reduced by pair-breaking as is the case for the Hebel-Slichter peak.
