Study the shapes of nuclei for heavy elements with mass number equal to (226 ≤ A ≤ 252)‎ through determination of deformation parameters for two elements (U and Cf)‎

الملخص EN

The current paper focuses on the studying the forms of (even-even) nuclei for the heavy elements with mass numbers in the range from (A = 226 - 252) for (226_292U and 244-2||Cf) isotopes.

This work will consist of studying deformation parameters (fi2) which is deduced from the "Reduced Electric Transition Probability" B (E2) t which is in its turn dependent on the first Excited State (2 +).

The "Intrinsic Electric Quadnipole Moments" (non-spherical charge distribution) (< ? 0) were also calculated.

In addition to that the Roots Mean Square Radii (Isotope Shift) < r2 >1 / 2 are accounted for in order to compare them with the theoretical results.

The difference and variation in shapes of nuclei for the selected isotopes were detected using 3D-plots for them (with symmetric axes); a 2D-plot were also used for each isotope to discriminate between them by the values of semi-major is equal (a) axes and semi minor is equal (b) axes.
