| Outline of Final Research Achievements |
It was found that ions and electrons associated with the ionization of gas molecule were generated in the nitrogen gas atmosphere during electron beam (EB) irradiation, and the generated ions were found to be N2+ ions. This result indicates that not only gas but also ions are present in the gas environment during EB irradiation. When Cr2O3 was kept in this atmosphere, it was found to be nitrided. Researchers should consider the effect of ions when observing specimens in a gas atmosphere during EB irradiation.
