摘要：

In phonon-propagation studies using heat pulses it has been found that predominantly transverse phonons are observed for [100] propagation in LiF whereas mainly longitudinal phonons are observed for this direction in KCl. This result and similar effects previously reported on other crystals are explained in terms of a phonon-focusing effect that arises from elastic anisotropy. © 1969 The American Physical Society.
