Abstract
The results of hard X-ray/soft gamma-ray observations of GX 339-4 with GRANAT/SIGMA are reported. The spectral and temporal properties of th e source during its four successive hard X-ray outbursts in 1990 - 199 4 were studied in details. We suggest that the mechanism of GX 339-4 o utbursts is triggering of the irradiation - driven instability in the low mass binary system.
