Kikuchi Physics.|kɪˈkuːtʃɪ|
[Name of Seishi Kikuchi (b. 1902), Japanese physicist, who first observed the lines.]
Kikuchi line: each of a series of lines in electron diffraction patterns which are attributed to the elastic scattering of previously inelastically scattered electrons and may be used to determine the orientation of crystalline specimens; so Kikuchi pattern.
1934Physical Rev. XLV. 43/1 The [electron scattering] patterns from stibnite consist of spots, Kikuchi lines, bands, circles and parabolas. 1948Proc. Physical Soc. LX. 343 The elementary diffraction theory for single scattering also leads to a Kikuchi-line breadth proportional to the corresponding plane spacing d/n. 1966D. G. Brandon Mod. Techniques Metallogr. ii. 113 Kikuchi line patterns can be used to give a more accurate estimate of the specimen orientation than can be determined from the normal spot pattern. 1968Mineral. Abstr. XIX. 83/2 A simplified stereographic projection from a Kikuchi pattern is used to determine the orientation of a crystal. 1970New Scientist 23 July 176/2 Kikuchi patterns, well known to users of the transmission electron microscope. |
