In a recent decade, experimental and theoretical studies on superionic conductors have been rapidly developed in the field of solid state physics. In this paper, after a classification of superionic conductors was given, the structures belonging to the main material groups are summerized and then the studies on dynamics of ions in the superionic conductors mainly by the neutron scattering method are reviewed.

The crystal structure of yeast phenylalanine transfer RNA in the monoclinic form has been solved at 2.5Å resolution. The entire model was initially built into the 3.0Å map based on the multiple isomorphous replacement method, and later rebuilt through a series of cycles of 2F_o-F_c maps at 2.5Å resolution omitting oligonucleotide segments of 3-10 residues at a time. The improved model coordinates have been subjected to several rounds of difference synthesis refinement that have reduced the R value from 0.470 to 0.274.

A difference cylindrically symmetrical Patterson function is introduced and theorems concerning it are given. The difference function has advantage in several respects in structure analysis of fibre materials compared to the usual cylindrically symmetrical Patterson function. It can be calculated without the intensity data on the equator, and was very useful in structure analysis of the thin filament of crab striated muscle in rigor made by the authors. Outline of the analysis is described.
