We present the detection of 661 known pulsars observed with the AustralianSKA Pathfinder (ASKAP) telescope at 888 MHz as a part of the Rapid ASKAPContinuum Survey (RACS). Detections were made through astrometric coincidenceand we estimate the false alarm rate of our sample to be ~0.5%. Using archivaldata at 400 and 1400 MHz, we estimate the power law spectral indices for thepulsars in our sample and find that the mean spectral index is -1.78 +/- 0.6.However, we also find that a single power law is inadequate to model all theobserved spectra. With the addition of the flux densities between 150 MHz and 3GHz from various imaging surveys, we find that up to 40% of our sample showsdeviations from a simple power law model. Using Stokes V measurements from theRACS data, we measured the circular polarization fraction for 9% of our sampleand find that the mean polarization fraction is ~10% (consistent betweendetections and upper limits). Using the dispersion measure (DM) deriveddistance we estimate the pseudo luminosity of the pulsars and do not find anystrong evidence for a correlation with the pulsars' intrinsic properties.
