Résumé :

The microscopic energy density method is applied to the study of nuclei with N ≥ 50 and Z = 32-40. The experimental Subshell effect at N = 56, which is not found in many previous works about this region, is well reproduced by the present self-consistent calculation. The existence of strongly deformed prolate isotopes of Zr and Sr for N ≥ 60 is also explained. A wide region of oblate shapes is predicted for N ≥ 60 and Z ≤ 36. The results also support the interpretation of low-energy isomers in the shape transition region as shape isomers. © 1981.
