摘要：

Elastic properties of the dense Kondo compounds CeNiSn and CePdSn with orthorhombic structure have been investigated by the ultrasonic measurements. The anomalous softening of the longitudinal C11, C22 and C33 modes in CeNiSn is responsible for the energy gap at the Fermi level in the quasiparticle band. A remarkable anisotropic behavior on the resistivity as well as the elastic constant in the magnetic field along the crystallographic a, b, c-axes has been observed. In CePdSn, the softening in the longitudinal C22 and C33 modes has been found.
