| Outline of Final Research Achievements |
By extracting the interference phenomenon of itinerant electrons with set of lattice planes, we could demonstrate the validity of the Hume-Rothery-type phase stabilization mechanism, regardless of the degree of metallic, covalent and ionic bonding types involved. We have also succeeded in reliably determining the number of itinerant electrons per atom, e/a, for 54 elements in the periodic table. It covers 3d-, 4d- and 5d-transition metal elements. The results have been reported as a book entitled "The Physics of the Hume-Rothery Electron Concentration Rule" in Japanese (Uchida Rokakuho, Japan, 2015) and also as the review article in English ("Crystals", 7, 1-112, doi:10.3390/cryst7010009).
