Measurements have been made on the concentrations of vacancies and interstitial clusters in singlecrystal graphite irradiated with neutrons in a reactor and with carbon ions in an accelerator. The irradiations were carried out over a range of temperatures from 30" to 1100°C and a range of total init

✦ Synopsis
In continuation of a study of the electronic properties of neutron irradiated carbons the resulting changes in their electronic properties (electrical resistivity, Hall effect, magnetoresistivity, magnetic susceptibility) were determined after various thermal anneals. Similarities in behaviour of PGCCL and graphite are observed. The pyrocarbon which is damaged most easily recovers its initial properties with the most difficulty, however, the previous damage does not affect its behaviour during graphitisation. Previously started measurements of the electron spin resonance have been completed.
