Elliptical carbon onions were produced from amorphous carbon by electron beam irradiation. Atomic structure and
structural stability of the onion were investigated by high-resolution electron microscopy, molecular mechanics
calculation and molecular orbital calculation, and a structure model of 
@
was proposed
at the center of the elliptical onion.
