    "abstract": "The cold(neutronless) fission of $^{252}$Cf is studied in the frame of a\nmolecular model in which the scission configuration is described by two aligned\nfragments interacting by means of Coulomb (+ nuclear) forces. The study is\ncarried out for different distances between the fragments tips and excitation\nenergies. For a given deformation, the fragment\u0027s total energy is computed via\nthe constrained Hartree-Fock + BCS formalism. The total excitation energy\npresent in the fragments is supposed to contribute only to the fragments\ndeformation and the asymptotic value of the kinetic energy is equated to the\ninter-fragment potential at scission. These two constraints yield not more than\none or two fission channels for a fixed tip distance and excitation energy.\nDiscarding those fission channels corresponding to a disequilibrated sharing of\nthe excitation energy between the two fragments, we were able to establish the\nmost likely scission configurations for a specified excitation energy.",
