In the previous paper (SunQM-5), we developed a brand new nuclear {N,n//6} QM. In current paper, we used the nuclear {N,n//6} QM to analyze how a (Sun-like) star quantum collapses from {0,2} to a black hole {-5,1} QM structure. Two different atom-based models have been proposed and analyzed. In the “atom shrink model”, a Sun {0,2} quantum collapse to {-5,1}, shrink by ΔN = -5 plus Δn = -1, was explained as directly caused by the shrink of hydrogen atom {-12,1}o (or e1{0,1}o) orbital shell by ΔN = -5 plus Δn = -1 to a quark-sized virtual atom {-17,1} (or e1{-5,1}), with fixed (or unchanged) total number of (virtual) atoms. In the “atom fusion model”, a celestial body’s quantum collapse was explained as that it was caused by the fusion of atoms, from H, to He, C, O, Ne, Fe, Og, then to the (pseudo) Z number = 3E+5, 1.2E+13, 1.25E+21, up to 4.5E+56, until all protons are merged with electrons, so that the whole Sun become a single gigantic atom with a single nucleus containing 1.19E+57 neutrons (= Sun mass / proton mass), and with zero proton or electron left. Our {N,n} QM analysis revealed that the super heavy elements (Z >> 118) are formed during the quantum collapse of {-1,1} white dwarf to {-2,1} sized celestial bodies. So on a pre-neutron star (like a {-2,1} = {-3,6} sized celestial body) that right before quantum collapse (or explode) into a {-3,2} sized neutron star, the atoms in the out-edge shell within the {-3,6} sized (solid) celestial body are all super heavy atom with Z ≥ 118. This is because under the super high G-pressure, the equilibrium reaction of “nuclear fusion <=> nuclear fission” shifted to the fusion side. During the neutron star explosion, part of these (super heavy) atoms in the out-edge shell is exploded away. Then these (exploded away) super heavy atoms start to fission into smaller atoms (after the super high G-pressure is released, and the equilibrium reaction shifted to the fission side). If this model’s result is meaningful, then most (if not all) of heavy atoms in our daily-world (from Co (Z=27) to U (Z=92) or even heavier) are the product of nuclear fission (rather than the nuclear fusion) reaction of the previous Z > 118 atoms right after the neutron star explosion.
