Abstract
CLEAR transparent solutions of soaps and detergents give characteristic X-ray patterns, due to the colloidal micelles formed by association of ions or molecules or both. There is still, however, no agreement about the number and kinds of micelles which can be present1. Hess and Gunderman2 were the first to explain the X-ray patterns upon the basis of lamellar micelles consisting of double layers of molecules separated by equally spaced layers of water. Harkins3 recently directed attention to a so-called 'M-band' in the pattern and attributed it to diffraction from the double-leaflet alone.
