  We utilize the generalized contact formalism in conjunction with the
Woods-Saxon mean-field description of the long-range part of the nuclear wave
function to assess the relative prevalence of short-range correlation pairs
within atomic nuclei. We validate our approach by fitting experimental charge
density results and electron scattering experiments to a very good agreement.
Applying our model, we calculate the spin-zero short-range correlations contact
ratios. Interestingly, for nuclei with $A>50$, we observe a notable dependence
on the neutron-to-proton ratio $N/Z$. Specifically, the probability per nucleon
to find neutron-neutron pairs increases, while that of proton-proton pairs
decreases, whereas the probability of finding neutron-proton pairs remains
relatively constant. To interpret this isospin symmetry breaking effect, we
employ a simple model based on generalized Levinger constants, linking it to
differences in nuclear proton and neutron radii.
