Abstract

The longitudinal ultrasonic attenuation at low temperatures for a d-wave superconducting order parameter is examined. The ratio of the superconducting to normal state attenuation, α_s/α_n, depends strongly on the direction of propagation of ultrasound with maxima corresponding to nodes of the order parameter on the Fermi surface. We propose that measurements of ultrasonic attenuation in a single crystal of the high-T_c superconductors can give the information regarding the position of nodes.
