Abstract
Three-beam normalised pump-probe measurements for the Z-localised vibrational mode of H- in LaF3 yield a 10K population decay time (T1) of 49 ps. The temperature decrease of this T1 time is fitted to two-phonon anharmonic decay together with one-phonon absorption to the 351cm-1 higher (X,Y)-mode. Two-pulse vibrational echo measurements yield a homogeneous line width of 0.3 cm-1. © 2001 Elsevier Science B.V. All rights reserved.
