MECHANICAL PROPERTIES OF SOME SINGLE METAL CRYSTALS 



(BRIDGMAN) 



All the following metals have an axis of rotational symmetry: Zn and Cd have a 6-fold 

 axis (hexagonal system); Bi, Sb, Te, 3-fold, trigonal; Sn, 4-fold, tetragonal. The rotational 

 axis is taken as the datum line. The notation of Voigt is used (Lehrbuch der Kristallphysik, 

 Berlin, 1910). Bridgman, Proc. Amer. Acad. Arts and Sci., 60, 305, 1925.
