摘要：

We survey the elastic scattering rates of neutralinos on many nuclei, incorporating LEP constraints and choosing model parameters that give a critical density of the lightest neutralino, using the odd-group model to estimate nuclear matrix elements and incorporating a simple model for the momentum dependence of the elastic spin and mass form factors. We find that the rates for elastic scattering on F-19 can be estimated reliably and are reasonably large for a relic mass, M-chi, in the range M-chi almost-equal-to 20-60 GeV. We present calculations of the elastic neutralino - F-19 scattering rates in regions of parameter space consistent with LEP and other laboratory experiments.
