摘要：

Ultrasonic measurements have been made between 2K and 200K for large-grained Al6Li4Cu quasi-crystal. The temperature dependence of the ultrasonic velocity shows an anomalous decrease below 50K with decreasing temperature. This anomaly may be related to the existence of quantum tunneling states of atoms. © 1990.
