Abstract
Measurements of dislocation dependent attenuation (αD) in Cu and Al are obscurred at temperatures below 50 K by the attenuation due to electron-phonon interactions (αE). This paper presents the measurements on Al and Cu single crystals in which αE is eliminated by using a magnetic field [MATH] ⊥ [MATH] perpendicular to the direction of propagation of the acoustic waves. Underdamped resonance peak in αD was obtained at 4.2 K in a slightly deformed Cu sample. The results are discussed in the framework of the Granato-Lücke theory.
