Corinthian order perhaps reduced in size and importance, scrolling out above the two ranks of stylized acanthus leaves and stalks ("cauliculi" or "caulicoles"), eight in all, and to notice that smaller volutes scroll inwards to meet each other on each side. The leaves may be quite stiff, schematic and dry, or they may be extravagantly drilled and undercut, naturalistic and spiky. In Late Antique and Byzantine practice, the leaves may be blown sideways, as if by the wind of Faith. Unlike the Doric and Ionic column capitals, a Corinthian capital has no neck beneath it, just a ring-like astragal molding or a
Ionic radius radii. The relation between soft-sphere ionic radii, formula_2 and formula_3, and formula_1, is given by formula_5, where formula_6 is an exponent that varies with the type of crystal structure. In the hard-sphere model, formula_6 would be 1, giving formula_8. In the soft-sphere model, formula_6 has a value between 1 and 2. For example, for crystals of group 1 halides with the sodium chloride structure, a value of 1.6667 gives good agreement with experiment. Some soft-sphere ionic radii are in the table. These radii are larger than the crystal radii given above (Li, 90 pm; Cl, 167 pm). Inter-ionic separations calculated
