COSMIC-RAY ISOTROPY AT ENERGIES ABOVE 10(18) EV

Studies have been made of the extent to which extragalactic cosmic rays observed at the earth would be deviated by the galactic magnetic field. The distribution of these deviations is presented as a function of observed direction for two field models. Also using these two models, possible extragalactic directions are derived for the cosmic rays detected by the SUGAR giant air shower array as a basis of a possible technique for searching for extragalactic cosmic ray sources.
