摘要
We report here the preliminary results of the search for gravitational wave bursts from the 2003 run of the EXPLORER-NAUTILUS experiment. The total common measuring time was 149 days. The detectors had a typical noise spectral amplitude of about 2 x 10(-21) Hz(-1/2), a bandwidth of the order of 10 Hz and a very good stability. We derive a new upper limit for the GW burst rate, of the order of 0.02 events/day for h(RSS) >= 2 x 10(-19), and discuss the implication of this result with respect to the results obtained with the 2001 run.
