Tetragonal $[T{_1}]$ and hexagonal $[H{_1}]$ Laue classes: transverse modes, backscattering

This table, written for the class $[T{_1}]$ , is also valid for the class $[H{_1}]$ with the additional relations $[c_{66} = {\textstyle{1 \over 2}}(c_{11} - c_{12})]$ ; $[p_{66} = {\textstyle{1 \over 2}}(p_{11} - p_{12})]$ .

$[\hat{\bf Q}]$	$[\hat{\bf u}]$	C	$[{\bf e}]$	$[{\bf e}']$	$[\beta]$
$[(0,1,1)/\sqrt 2 ]$		$[{\textstyle{1 \over 2}}(c_{44}^{} + c_{66}^{})]$		$[(0,1, - 1)/\sqrt 2 ]$	$[[(n_1^2 + n_3^2)^2 / 16n_1^4 n_3^4 C](n_1^2 p_{66}- n_3^2 p_{44}')_{}^2 ]$
