Scientific paper

The results of an ongoing search for pulsars in globular clusters and transient X-ray sources are presented. Since the discovery of the millisecond pulsar PSR 1821-24 in M28 one new pulsar was discovered, PSR 1620-26, in a binary system in the core of the globular cluster M4. Upper limits to pulsed emission are given for the 84 globular clusters and 3 X-ray transient sources observed. The paucity of new discoveries in globular clusters by this survey is considered. The inability to detect X-ray sources may be the result of processes related to their accretion disks. An improvement in sensitivity afforded by a planned software enhancement may reveal some pulsars in the objects observed.
