Kikuchin.

/kɪˈkuːtʃi/

Etymology: < the name of Seishi Kikuchi (1902–74), Japanese physicist, who first observed the lines.

Physics.

Kikuchi line n. 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.

1934 Physical Rev. 45 43/1 The [electron scattering] patterns from stibnite consist of spots, Kikuchi lines, bands, circles and parabolas.

1948 Proc. Physical Soc. 60 343 The elementary diffraction theory for single scattering also leads to a Kikuchi-line breadth proportional to the corresponding plane spacing d/n.
