Upper panel: ratio between the neutron capture rates at T = 2.5 108 K obtained with the D1M+QRPA+0lim (Goriely et al. 2018) and those obtained with the GLO (Kopecky & Uhl 1990; Capote et al. 2009) photon strength functions, for all the 793 nuclei with 14 ≤ Z ≤ 93 included in the i-process network and for which no experimental data exist. 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 obtained either with the D1M+QRPA+0lim or GLO photon strength functions. The black line corresponds to the difference in the overabundance between D1M+QRPA+0lim and GLO predictions.
