S>The effects of electron irradiation at 4 Mev on changes in the Young's modulus of pure pile graphite were studied. In all specimens measured there was no initial change in Young's modulus following the irradiation. On annealing, Young's modulus remained constant until a temperature of about 200 deg K was reached. Above this temperature there was a sharp inverse annealing peak with a maximum about 270 deg K. The height of the peak was found to vary as the square of the initial resistance change. As the irradiation dose was increased, the anomalous rise set in at a lower temperature and the peak developed a plateau on the hightemperature side. It coincided exactly with the inverse annealing peak observed in the annealing of thermal resistivity. (P.C.H.)
