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%.
