DETECTION OF X-RAY-BURSTS IN THE GLOBULAR-CLUSTER NGC-6652

Two type I X-ray bursts were detected from a position consistent with the transient X-ray source in NGC 6652 with the Wide Field Camera of t he BeppoSAX satellite, strongly suggesting that this transient is a ne utron star. Our detection brings to ten the number of X-ray sources in globular clusters in which a type I X-ray burst has been seen, out of twelve known bright sources. The statistical evidence that the fracti on of low-mass X-ray binaries which contain a black hole accretor is s maller in globular clusters than in the galactic disk is suggestive, b ut as yet not compelling.
