Density as a constraint and the separation of internal excitation energy in TDHF
We present a fast and efficient constrained Hartree-Fock iteration scheme which constraints the complete density distribution to remain constant. The scheme is particularly suited to a coordinate- or momentum-space representation. The technique is applied to separate the collective and the internal energy in a propagating TDHF state. We study the behavior of these two energies in an16O+16O collision.
The binding energy of 184 476 X in the droplet model
The positron spectrum emitted in the U-U-reaction at subthreshold energy could be interpreted in terms of the formation of a giant nucleus if the binding of the latter is 100 MeV stronger than predicted by the usual droplet model parametrisation. We analyse the extrapolation to giant nuclei by accounting properly for the error propagation when the parameters are fitted to measured binding energies and radii. The influence of higher order terms is discussed.
