Abstract

The electric quadrupole to magnetic dipole transition ratio E2/M1 for the reaction γN → Δ(1232) is calculated in a modified Skyrme model, which includes stabilizing fourth- and sixth-order terms. The coefficients of these terms are determined from vector meson couplings in the static limit; the other parameters are given by their physical values. We obtain for E2/M1 a negative sign and a magnitude which is consistent with the empirical value.
