摘要：

A direct search has been made for supermassive relics (heavier than about 10(12) GeV/c2) with a 2000-m2 array of CR-39 track-etch detectors deployed underground for 2.1 yr. The nonobservation of penetrating tracks places a new upper limit for the velocity-dependent flux at 3.2 x 10(-16) cm-2 s-1 sr-1, for magnetic monopoles carrying various magnetic charges, for electrically charged relics, and for strange matter. This flux limit corresponds to a limit on the relic abundance of order n(x)/n-gamma = 10(-29) relative to the 3-K photons.
