High resolution γ -ray spectroscopy measurements were performed in JET (3He) D plasmas with high energy ion populations driven by radio-frequency (RF) heating. One of the first reactions investigated was12C(3He,pγ)14N, which was observed at low3He concentrations. In order to interpret the measurements in this work, cross section data for the12C(3He,pγ)14N reaction are evaluated. Available data for the population of excited states in14N up to the eighth level are assessed in the range E3He=0-5 MeV. Discrepancies and gaps in the database have been solved by means of interpolations and consistency analysis. The evaluated cross section data are used to predict the intensity ratio of characteristic 2.31 and 1.63 MeV γ -rays. © 2010 EURATOM.
