摘要
The proton-capture reactions 12C(p,γ)13N and 13C(p,γ)14N have been studied to determine 13C enrichments. The system has been calibrated by measuring the gamma-rays yield from the 12C(p,γ)13N and 13C(p,γ)14N reactions as a function of known 13C enrichment.This technique is applicable to the analysis of samples with 13C enrichments between 1% and 90%.
