الملخص الإنجليزي

Nuclear shape, single particle states and ground states properties such as binding energy, two neutron separation energy (Sn2), and proton and neutron radii in the Cd isotopic chain are studied within the framework of relativistic mean field theory using nonlinear meson nucleon coupling model.

A systematic investigation of the ground state shape is also performed for Cd isotopes (Z=48, 47< N < 116).

The shape of the ground state for Cd isotopes varies between three categories: spherical, axial (prolate, oblate) and triaxial.

Our results suggest that the neutron deficient side of the chain exhibts an oblate-prolate transition, after that the shape fluctuations are between axial (oblate or prolate) and triaxial.

Single particle states are shown for nuclei, which have a jump in value of quadrupole deformation fi20 and neighboring nuclei.

Single particle states are in a good agreement with Nilsson Diagram for axial nuclei.he physical properties: Binding energy, two neutron energy, neutron, proton, and charge radii are studied as a function of mass number.

In general, a smooth change in these properties is found, except near A = 98, 130, 136, one can see a sharp change, which reflect the sudden change in the ground state deformation in the neighboring nuclei.

Our calculations shows a reasonable agreement with experimental data.
