Upper panel: representation in the (N, Z) plane of the ratio between the total (HF+DC) and the HF neutron capture rates at T = 2.5 10⁸ K for all the 793 nuclei with 14 ≤ Z ≤ 93 included in the i-process network and for which no experimental data exist. Black open squares correspond to stable nuclei. Lower panel: surface elemental overabundances resulting from the i-process in the 1 M_⊙, [Fe/H] = −2.5 model star when adopting TALYS radiative neutron-capture rates excluding (HF) or including (HF+DC) the DC component to the reaction mechanism. The black line corresponds to the difference in the overabundance between HF+DC and DC predictions.
