摘要
从坐标变换出发,导出了布里渊散射张量转动修正的简洁表达式。给出了各晶系晶体一般声学模及高对称方向纯模的散射张量转动修正的确切形式。说明了结果的自洽性,并从物理上对转动修正的各种情形作了讨论。
A general formula for the rotational correction of Brillouin scattering tensor is derived based on the coordinate transformation. The exact rotational correction of the scattering tensor related to general acoustic modes and pure modes in the higher symmetry directions, for different crystal systems, is presented. The selfconsistency of the result is explained. The rotational correction in connection with various cases is physically discussed.
