Resumen *

The predictive power of the outer gap model of high-energy emission from pulsars is used to analyze the Parkes multibeam pulsar survey. We find that most of the radio pulsars of the Parkes catalog are not γ-ray emitters according to the outer gap model. The sample of possible new γ-ray pulsar detections by AGILE and GLAST is given. That includes 13 new excellent candidates. Four new positional coincidences between EGRET detections and Parkes pulsars are found, for which we discard a physical association. The consequences of applying a new electron density model for assigning the pulsar distances are explored. The new model systematically reduces the distances to the pulsars (corrections can be as large as 90%), increasing their fluxes and affecting the detection prospects.
