ABSTRACT

The BeppoSAX Narrow Field Instruments observed the galactic source GS 1826-238 in October 1997 , following a hard X-ray burst with a peak flux of about 100 mCrab detected by BATSE .
Two short X-ray bursts ( \sim 150 seconds ) were detected up to 60 keV , with larger amplitude and duration at lower energies ( up to a factor 20 times the persistent emission ) .
This confirms the proposed identification of the source as a weakly magnetized neutron star in a LMXRB system .
For both persistent and burst states , the spectrum in the 0.4-100 keV energy range is well fitted by an absorbed black body , plus a flat power-law ( \Gamma \sim 1.7 ) with an exponential cutoff at 50 keV .
