A systematic analysis of the $\alpha$ + core structure is performed in ground state bands even-even nuclei $22 \leq Z 42$ region terms Local Potential Model. The interaction described by nuclear potential (1 Gaussian)$\times$(W.S. W.S.$^3$) shape with 2 free parameters. Properties such as energy levels, reduced $\alpha$-widths, $B(E2)$ transition rates and rms charge radii are calculated compared experimental data. good agreement data obtained general, even for without {doubly closed shell core} configuration. selected indicates that $^{44}$Ti $^{94}$Mo have a greater $\alpha$-clustering degree comparison their respective neighboring this set. In addition, model points to existence configuration significant $^{44}$Ti, $^{60}$Zn, $^{94}$Mo. study shows approach satisfactorily applicable other than those above double-shell closures.
