We present an analysis of the X-ray emission for a complete sample of 288Abell clusters spanning the redshift range 0.016<= z <= 0.09 from the ROSATAll-Sky Survey. This sample is based on our 20cm VLA survey of nearby Abellclusters. We find an X-ray detection rate of 83%. We report cluster X-rayfluxes and luminosities and two different flux ratios indicative of theconcentration and extent of the emission. We examine correlations between theX-ray luminosity, Abell Richness, and Bautz-Morgan and Rood-Sastry clustermorphologies. We find a strong correlation between Lx and cluster richnesscoupled to a dependence on the optical morphological type. These results areconsistent with the observed scatter between X-ray luminosity and temperatureand a large fraction of cooling flows. For each cluster field we also reportthe positions, peak X-ray fluxes, and flux-ratios of all X-ray peaks above3-sigma significance within a box of 2x2 Mpc centered on Abell's position.Comment: 59 pages including 3 tables, + 10 figures.
