Abstract
An aluminum single crystal has been irradiated at 4.6 K with fast neutrons to a Frenkel defect concentration of 810 ppm. Inelastic neutron scattering experiments revealed a clear shift of the [] transverse phonon frequencies with respect to the annealed crystal. In contrast to theoretical predictions, no obvious resonancelike behavior has been observed in the wave-vector range ( is in reduced units).
