الملخص الإنجليزي

Binding and excitation energies have been calculated at low lying levels for ^gNe^o , 16^14 and i4Si16 nuclei using shell-model calculation with two protons in the S-d shell for 18Ne10 , and 16S14 while two neutrons for 14Si16 in orbits outside the closed core.

The effective two-body matrix elements are obtained from the USDA, USDB and (USD) potential interaction.

Results of calculated binding and excitation energies are show a good agreement with experimental data with calculated by using theoretical matrix elements .

The shell model calculation is used to investigate properties of levels at low lying in the mass number of nuclei A =18 and 30.

An inert core with a residual two-particle interaction between the outer nucleons of 18O8 ,, and 14Si14 as summed.

For the positive parity states all configurations in the s-d shell are taken into account are described by a closed shell, two nucleons in the S-d shell .The effective two-particle interaction is chosen to be a described by the USD,USDA ,and USDB potential.

Good agreement with experiment is obtained for the binding and excitation energies.

It is considered USDA , USDB and USD potential for two-body matrix element interaction as the most input parameters to the calculation is the nuclear energies, which contains realistic two (N-N) interactions.

Provided the calculation is performed in a large enough basis space, the ground-state energy will converge.
