The experimental investigation of the structure of atomic nuclei reveals the presence of different shapes as, for example, spherical or ellipsoidal. The latter can have sizable deviation (i.e., deformation) with respect to the spherical shape. Nuclear deformation is found especially far from the magic numbers of nuclear stability. The evolution of nuclear shapes in different regions of the...

53. Microscopic description of fission process including intrinsic excitations

The microscopic description of fission is very challenging due to the numerous degrees of freedom involved in the process: collectivity, pairing, individual excitations, dynamical effects. Furthermore, this phenomenon happens in heavy nuclei in which the number of nucleons prevents from an exact solution to the many-body problem. Several approaches based on mean-field approximations have been...

72. Lifetime measurement of 235U fission products using Doppler-shift methods

The fission process leads to excited states in neutron rich nuclei at high spin and excitation energy. Obtaining new data for nuclear lifetimes and transition probabilities is a step towards a better understanding of the structure of neutron-rich nuclei and nuclear theory, in general. This presentation deals with the use of the Doppler-shift Attenuation Method (DSAM) coupled with the...
