Abstract

An off-line release study 13N(T 1 2 = 9.96 min) produced by proton induced reaction on a graphite target (POCO-graphite EDM3, density = 1.84 g/cm3, grain size /t 3 μm) has been performed. The activation energy for the diffusion process is determined to be 6.15(16)×105 J/mol. With this activation energy, extraction efficiencies for 13N are obtained at different temperatures and are compared to on-line measured extraction efficiencies.
