- | The preliminary results show the abundances of selected nuclides. The abundances are representative for the regions of magic neutron numbers 82 and 126. The abundances in these regions should be high. For $Y_e=0.15$ only small abundances for these nuclides are present, because the seed density consisting of almost the same number of protons and neutrons is too small. For $Y_e=0.25$ we see strong abundances of these nuclides, but foe higher $Y_e<0.4$ the neutron density is too small. Thus neutron capure is too slow and the heavy elements cannot be built. | + | The preliminary results show the abundances of selected nuclides.
