Electron microdiffraction patterns, obtained when a small electron probe with diameter of 10-15 Å is directed to run parallel to and outside a flat crystal surface, are sensitive to the surface nature of the crystals. Dynamical diffraction calculations have shown that most of the experimental observations for a flat (100) face of a MgO crystal, such as the streaking of the central spot in the surface normal direction and (100)-type forbidden reflections etc., could be explained satisfactorily by assuming a modified image potential field outside the crystal surface. However the origin of this extended surface potential remains uncertain. A theoretical analysis by Howie et al suggests that the surface image potential should have a form different from above-mentioned image potential and also be smaller by several orders of magnitude. Nevertheless the surface potential distribution may in practice be modified in various ways, such as by the adsorption of a monolayer of gas molecules.

Summary1. Caseinolytic and fibrinolytic systems for assay of plasmin in fibrinolytic agents are described which are based upon the determinations of AE/min during the linear portion of the casein-plasmin and fibrin-plasmin reaction curves respectively. A " caseinolytic-rate " unit and “fibrinolytic-rate " unit of ÄE/min × 103 during the linear portion of the respective curves are proposed.2. Data are presented indicating that a reliably linear relationship exists between plasmin concentration and these caseinolytic - and fibrinolytic-rate units.3. Data comparing results obtained with the proposed assay techniques and previously-used casein and fibrinolytic techniques are presented.4. Formulae by which caseinolytic-rate and fibrinolytic-rate units can be roughly converted into Remmert-Cohen type plasmin units are offered.5. The theoretical and practical problems which have influenced development of assays for fibrinolytic components are discussed.6. The advantages of the plasmin “rate unit” techniques vis a vis existing assays are delineated.7. The potential application of the techniques to measurements other than the plasmin content of fibrinolytic agents is discussed.
