The Nautilus g.w. detector and the interaction with cosmic rays

• Thermo-acustical model of interaction of cosmic rays with a bar detector (Liu-Barish, De Rujula, Cabibbo, Amaldi-Pizzella)

• “Expected” result for low-amplitude signals October 98-Jan 99 (Phys. Rev Lett. 84, 2000)

• “Unexpected” result for high-amplitude signals (Phys. Lett. B 499, 2001 , Phys. Lett. B 540, 2002 ) , when Al is superconducting
