Abstract
Polycrystalline C-60 samples irradiated with five doses of nuclear rea ctor neutrons stretching from 2.44 X 10(14) to 1.03 X 10(18) n/cm(2) w ere investigated by positron annihilation spectroscopy and DSC. The me asurements indicated that the crystal structure of buckminsterfulleren e is unaffected up to a dose of about 7.56 X 10(16) n/cm(2). Above tha t dose the crystal lattice begins to collapse and at a dose of 1.03 X 10(18) n/cm(2) the structure becomes totally disordered.
