The indexing ambiguity in serial femtosecond crystallography (SFX) resolved using an expectation maximization algorithm

Autor: Haiguang Liu, John C.H. Spence

Publikováno v: IUCrJ, Vol 1, Iss 6, Pp 393-401 (2014)

Crystallographic auto-indexing algorithms provide crystal orientations and unit-cell parameters and assign Miller indices based on the geometric relations between the Bragg peaks observed in diffraction patterns. However, if the Bravais symmetry is h

Reprint of: Inversion of dynamical Bragg intensities to complex structure factors by iterated projections. For Ultramic. 2020. ('Pico' Festschrift, May 2021)

Autor: John C.H. Spence, Jeffrey J. Donatelli

A method for recovering complex structure factors from many simultaneously excited Bragg beam in- tensities is described. The method is applied to simulated transmission electron diffraction data over a wide range of crystal thickness and beam energi
