Scientific paper

The high frequency survey for pulsars by Johnston et al. (1992a) discovered 46 new pulsars. Following their discovery, regular timing observations at the Parkes radio telescope have been carried out to obtain improved parameters for them. One of these pulsars was found to be in a highly eccentric orbit around a Be star and is reported elsewhere (Johnston et al. 1992b, 1994). We report here on the remaining 45 pulsars. One, PSR J1803-2712, is a member of a binary with a wide, circular orbit and a low mass companion. As in the comparable northern survey by Clifton et al. (1992), a substantial number of the new pulsars have ages less than 10^5^yr. Two of these young pulsars may be associated with supernova remnants and three have glitched within the past three years.
