N2 - Results from a preliminary accelerator-based experiment conducted at the Harwell Tandem Van de Graaff generator to estimate the thick target integrated over angle yield of 6.129 MeV γ-rays from α-particles in the MeV range stopping in natural carbon are briefly outlined. The results should be useful in planning future detailed experiments to generate data for applications and also to benchmark thin target cross section evaluations. The estimated yields referred to a natural 13C abundance of 1.09 atom % at 5.597, 5.801, and 5.999 MeV in units of 6.129 MeV γ-rays per 108 α-particles are: 1.04, 1.62 and 3.31, respectively. An indicative overall relative uncertainty at the 68 % confidence level is estimated to be about 6%, although we caution that, being undertaken only as a feasibility study, the checks and balances we would usually conduct were not performed.
