Crystallography in the Spaces Esup2/sup, Esup3/sup, Esup4/sup, Esup5/sup...Nsup0/supII Isomorphism Classes and Study of Five Crystal Families of Space Esup5/sup

摘要

In the paper N0II, we describe some isomorphism classes and we apply their properties to the study of five crystal families of space E5. The names of these families are the following ones (monoclinic di iso squares)-al, decadic-al, (monoclinic di iso hexagons)-al, (rhombotopic cosa=-1/4)-al and rhombotopic cosa=-1/5. The meaning of these names will be given in Paragraphs 5 and 6 with some geometric properties of their cell.
