Description
The non-fissility with thermal neutrons of the 238 uranium system results from the too small clusterization energy E(cl) created when the system changes into 208 lead + 31 neon or 209 lead + 30 neon. Indeed, it becomes fissile only when E(cl), at the most equal to 49.97 MeV at E(n) = 0, reaches 51.47 MeV at E(n) = 1.5 MeV. We suggest that this fissility does not simply result from a core-cluster collision destroying the lead core, since E(cl) is too small for overcoming the corresponding Coulomb barrier of 88.33 MeV, but rather from a combined shifting of the 82 protons of the lead core against the whole neutron phase, i.e. from a four-phonon giant dipole resonance, since E(cl) reaches about four times the G.D.R. energy of 238 uranium. We suggest that this 4-phonon G.D.R. triggers the nucleon phase of the fission reaction, a phase characterized by an uncertainty in the energy as great as 3.87 GeV, the ephemeral disappearance of any proton charge, and a lifetime of 0.17 ys.
