Classical mechanics and Time Dependent Hartree-Fock (TDHF) calculations of heavy
ions collisions are
performed to study the rotation of a deformed nucleus in the Coulomb
field of a collision partner. We show that this Coulomb reorientation is
independent on the charges and the relative energy of the partners. It
only depends upon the deformations and the respective masses. Furthermore
this reorientation modifies strongly the fusion cross-section around the barrier for light
deformed nuclei on heavy collision partners. For such
nuclei a hindrance of the sub-barrier fusion is predicted. |
