In this study, to calculate the isotope radii of strontium ( 78-100Sr), the deformation coefficients which depend on (b2,d) and the root mean square radius ( )are calculated. The main and secondary elliptical parts( a, b) , with the difference between them (ΔR)are taken. These parameters are calculated for the even-paired of78-100Sr isotopes (Z =38).The low transition probability B(E2) and the deformation parameters δ which in turn depend on the electric quadrupole moments arecalculated using the equations of the deformed coat model. The variety of shapes of the nuclei for the selected isotopes is observed by drawing three-dimensional (axially symmetric) shapes and two-dimensional shapes of strontium isotopes to distinguish between them using quasi-large (a) and quasi-small (b) Axes.
