Abstract:

The primary objective of the research was to determine the extent and nature of chemical changes produced in solid targets by fast heavy particle irradiation. The major portion of the work involved proton irradiation of solids using energy ranges from 0.7 to 2.5 MeV. Alpha particles and deuterons were also available and were used for special studies. In general, the results of the bombardments were evaluated with either electron spin resonance ESR or differential thermal analysis DTA techniques. The data provided by the ESR analytical methods tends to substantiate the conclusion that proton bombardment of diamond results in the formation of CH radicals. Furthermore, there is no doubt that H atoms can be trapped in the diamond lattice and will remain uncombined at liquid nitrogen temperature. Author
