英文摘要	Natural Science Foundation of the Education Department of Henan province of China [2009B590001]; Henan Science and Technology Agency of china [092102210314, 132102210207, 14B140010]; Open Project of State Key Laboratory of Superhard Materials (Jilin University) [201107]; National Natural Science Foundation of China [11104127]; Program for Innovative Research in University of Henan Province [13IRTSTHN020]; The acoustic waves in Li are investigated by solving the Christoffel equations. Theoretical calculations of the three dimensional slowness surfaces give insights into the mixing of longitudinal and transverse modes and show the origin of the phonon caustics. The results are explained in terms of phonon focusing due to the anisotropy of crystals. The propagation of elastic waves in Li is affected by the elastic anisotropy of the lattice.
