Abstract

• The shape evolution for some selected germanium isotopes have been investigated from calculated potential energy surfaces on beta-gamma     plane and analyzed by the single-particle energy levels. The Ev8 program with a 3-dimensional Cartesian mesh which solves the Skyrme-HartreeFock+BCS problem is employed. From the     plane, these results are pointed out that 64Ge is to be triaxial while both 68Ge (oblate) and 78Ge (prolate) have axially symmetric whereas 82Ge gives the spherical nature. The calculated binding energies of all selected nuclei in this work fairly agree with experimental data.
