MEAN-FIELD ON A 3-DIMENSIONAL MESH

In this talk we present the main ingredients of the mean-field method based on the Skyrme effective interactions that we have developed in t he last years. In particular, we show how the correlations beyond the mean-field approach are introduced. The range of applications of the m ethod is illustrated by the studies of the superdeformed nuclei, the d eformed nuclei up to the drip lines and of the influence of the giant dipole resonance on the dipole transitions between the low lying level s in the deformed nuclei.
