Abstract

Perturbed angular correlation measurements of111In in hexagonal La2O3 and Nd2O3 yield well defined symmetric electric field gradients with coupling constantv Q =280 MHz (extrapolated) in La2O3 andv Q =269 MHz for Nd2O3 at room temperature. The coupling constant in La2O3 linearly decreases with temperature. The spectra of La2O3, strongly damped at RT, rise to full amplitude at 870 K indicating dynamical interactions.
