We obtain a good agreement between the calculated and experimental data, particularly for the dip at $^{48}$Ca. A direct correlation between nuclear size and electric monopole transitions is established to compute the electric monopole transition strengths, $\\rho^2(E0)$. We further study the isotopic shift for the even-even $^{32-46}$Ar and $^{44-50}$Ti isotopes.","authors_text":"B. Maheshwari, K. Nomura, P.
