When crystals are distorted periodically by a vibrating force, transitions take place among nuclear Zeeman levels of Δm=±2 in the rotating frame. This excitation is observed as the reduction in relaxation times of spin-locked magnetization. Unlike ultrasonic excitation in the laboratory frame, the acoustic frequency is low (2γH1⁄2π), and this fact, together with a high sensitivity to a strain, enables one to determine the electric field gradient-elastic tensors s accurately. These effects have been demonstrated for Na in NaCl single crystals. Measurements for several orientations of the force and the external magnetic field have yielded S11=(2.8±0.3)×1015 statcoul/cm3 and S44=−(0.81±0.08)×1015 statcoul/cm3. These values are explained by a consideration of overlap effects in addition to ionic point-charges.
