The measured strain corresponds to a length distortion MUCH smaller than the width of one atom. An atom is about 1 angstrom in linear size, while a proton is 1

The measured strain corresponds to a length distortion MUCH smaller than the width of one atom. An atom is about 1 angstrom in linear size, while a proton is 1/10000 that. The measured distortion corresponds to a distance smaller than that of a proton.
