Abstract
We present deep ATCA radio images of the globular cluster 47 Tucanae made a t 1.4 and 1.7 GHz and identify 9 compact sources in the cluster core with 1 1 pulsars. At present there are several pulsars for which pulse timing anal yses have not yet yielded precise positions. We examine other sources in th e image, and on the basis of their spectral index find two that would possi bly correspond to the pulsars with undetermined positions.
