We use an instantonic approach to calculate the asymptotic behavior of higher orders of the (4-∈)-expansion for the scaling function of the pair correlator of the O(n)-syrnmetric φ4-theory in the minimal subtraction scheme. Our results differ substantially from the known exact expression for the ∈3 order of the expansion of the scaling function in the small-τ domain.
