AB  - We have measured the size of the localized electron emission sites on multiwalled 
      carbon nanotubes (MWNTs) with caps closed by a fullerenelike structure. MWNTs 
      were individually mounted on tungsten support tips and imaged with a field 
      emission microscope (FEM). The magnification of the FEM was calibrated using 
      electron ray tracing and verified by comparing transmission electron microscope 
      images. The FEM image was also tested for effects of the lateral energy spread. 
      We found ring-shaped emission areas with three flattened sides, of a radius of 
      1.7+/-0.3 nm, and separated by 5+/-1 nm.
