Abstract
The sensitivity of a resonant gravitational wave (GW) antenna is calculated in terms of spectral density and frequency bandwidth. For a quantum-limited detector the bandwidth might reach values greater than 100 Hz, with a sensitivity to bursts of . The spectral amplitude sensitivity for the Nautilus detector has been measured to be and its target value is . Using two near-Nautilus detectors the GW stochastic background can be measured with a sensitivity, with respect to the critical density, of a few for an integration time of one year, as shown by simulations.Keywords
