Abstract
We report new measurements of the acoustic excitation of an Al5056 superconductive bar when hit by an electron beam, in a previously unexplored temperature range, down to 0.35Â K. These data, analyzed together with previous results of a dedicated experiment obtained for T>0.54K, show a vibrational response enhanced by a factor â¼4.9 with respect to that measured in the normal state. This enhancement explains the anomalous large signals due to cosmic rays previously detected in the NAUTILUS gravitational wave detector.
