摘要：

We study the development of collectivity in neutron rich nuclei in the close vicinity of Ni-78. We report on the large scale shell model calculations in the N = 52-54 even-even nuclei with Z = 30-36. We predict maximum of triaxiality in Ge-86 and explain this phenomenon on the basis of a pseudo-SU(3) symmetry interpretation. For the cases where signs for nonaxial shapes appear, we perform the triaxial Gogny calculations with particle number and angular momentum projections. The comparison of results obtained in the laboratory and intrinsic frames provides a comprehensive and complete picture of nuclear deformation in this region.
