P. Astone et al., UPPER LIMIT FOR A GRAVITATIONAL-WAVE STOCHASTIC BACKGROUND WITH THE EXPLORER AND NAUTILUS RESONANT DETECTORS, Physics letters. Section B, 385(1-4), 1996, pp. 421-424
We discuss the sensitivity of resonant-mass gravitational-wave detecto
rs to a cosmic stochastic background of gravitational waves. We report
the experimental upper limits given by the gravitational wave detecto
rs EXPLORER and NAUTILUS.
