Main i-process path (starting from ⁵⁶Fe) in the M1.0z2.3 (blue arrows) and M2.0z3.0 model (green arrows), at the bottom of the pulse, at the time of maximum neutron density (N_n = 2.19 × 10¹⁵ and 6.76 × 10¹³ cm⁻³, respectively). The dashed lines show the secondary paths, where at least 30% of the total flux goes. The four panels corresponds to four different zones in the (N, Z) plane. The black squares highlight the stable nuclei. The abundances of the M1.0z2.3 model are shown by the red colour scale in mass fraction.
