  A BeppoSAX survey of bright Neutron Star (NS) systems in globular clusters,
together with the results obtained on Galactic LMXRB, suggests that a
two-component model is a reasonable description of the 0.1-200 keV spectra. At
energies lower than a few keV, a thermal component dominates, either due to the
direct view of the NS surface, to the emission of the boundary layer, or to a
multi-temperature blackbody originating in the accretion disk. At higher
energies, a power-law with an high-energy cutoff is the likely signature of
thermal Comptonization of soft X-ray photons, probably produced by the same
thermal mechanisms as above. The plasma optical depth (electron temperature)
correlates (anticorrelates) with the X-ray luminosity, suggesting that the
properties of the Comptonizing plasma are driven by the X-ray energy output.
