Abstract The (ΔΔ)-component of the deuteron is investigated using π- and ϱ-exchange for the (NN → ΔΔ)-transition interaction. The depedence of the strength of the (ΔΔ)-component on thetype of regularization, the cut-off parameter and the normal deuteron wave functions is discussed. Inclusion of the ϱ-exchange leads to a weaker dependence on the cut-off parameter and to a smaller (ΔΔ)-admixture probability of 0.7 to 1.2 percent depending on the normal deuteron wave function for a cut-off parameter Λ = 5 fm−1.
