Anisotropic stress imprinting on 3D C60 polymers

abstract

We present synchrotron X-ray diffraction measurements performed on C60 samples quenched from 13GPa and 820K. The analysis of all the reciprocal space of a quenched sample shows that it consists of a 3-D arrangement of polymerised fullerene molecules. Moreover, it is shown that the intensity distribution in reciprocal space occurs in ellipsoidal surfaces instead of the normal spherical surfaces characteristic of a powder sample. This implies that the applied anisotropic stress is imprinted in the quenched transformed samples.
