摘要：

In the analysis of background events from a counter-technique experiment to study cosmic-ray nuclei above 8-GV rigidity two events were observed which are consistent with the assumption of Z14, A350, and 450 MeV/nucleon, and which cannot be acocunted for by more conventional background. Such events may be explained by the hypothesis of strange-quark matter (SQM). It is concluded that the existence of SQM has not been excluded by experiment at a flux level of 6×10-9 cm-2 s-1 sr-1. © 1990 The American Physical Society.
