Oxygen Coverage Measurment on Tungsten Surface by Neclear Microanalysis
Nuclear Microanalysis에 의한 텅스텐 표면의 산소 흡착조사
Abstract
The microanalysics by the direct observation of 180 (P, a)'" nuclear reactions on tungsten (110) surfaceare investigated using a 2MeV Van de Graaff accelerator. This method allows the determination of very smallquantities of nuclei near the surface of samples. The yields increase with oxygen exposure. The oxygen coverage, 0, is 0.5 at 5 Langmuir and 1.0 at 15 Langmuir.5 Langmuir.
