• The structure change of bismuth during the liquid-supercool-solid (LSS) transitionprocess was studied by using the energy scanning X-ray method. Through the LSSprocess, the position of the first peak in the radial distribution function (RDF) movesinside and the coordination number becomes smaller. Subpeaks on the right handside of the first peak become more pronounced and they are growing up to the figurejust before the solidification, which characterized RDF pattern like solid's. Theseresults were compared with the quasicrystalline model assuming the mixed structureof a hexagonal structure and a rhombohedral one. Consequently, it is suggested thatthere exists a pre-crystalline state with the rhombohedral structure not the same butsimilar to the solid one just before the solidification. By distorting slightly the pre-crystalline structure, we could simulate the solidification process.
