Tritium as a Source of Radiation in Electron Spin Resonance Studies

摘要: A common difficulty encountered in electron-apin-reso nance investigations of materials irradiated by high-energy radiations is the appearance electron-spin-resonance spectrum glass or quartz tubes containing samples. This was avoided using internally emitted T beta particles se source. Solutions tritium oxide water, deuterinm and plus deuterium mixtures with activities 100 mc/ nil 1 curie/nil, were frozen liquid nitrogen, spectra samples examined at liquid- nitrogen temperature. After applying doses radiation up to 5 x lO/sup 20/ sv/ ml, no effects on electron-spin-resonsnce observed. (C.H.)
