摘要
观测了低能质子在含Ｃ和Ｎ样品上引起的共振核反应。通过测定几种已知丰度富集物的γ射线产额进行体系刻度，可快速、准确地求出待测样品的丰度。测量范围：１３Ｃ为１％—９０％，１５Ｎ为０．０５％—５％。
The low energy resonance reaction on the samples containing C and N were studied experimentally.The system was calibrated by measuring the γ rays yield from the reaction as a function of known enrichment, using the experimentally determined calibration curve unknown specimens can be analysed. The measurable isotopic contents the range of 1%—90% for 13 C and 0 05%—5% for 15 N,respectively.
