heal.abstract	The magnetic dipole, the electric quadrupole and the Coulomb quadrupoleamplitudes for the transition \gamma N\to \Delta are calculated in quenchedlattice QCD at \beta=6.0 with Wilson fermions. Using a new method combining anoptimal combination of interpolating fields for the $\Delta$ and anoverconstrained analysis, we obtain statistically accurate results for thedipole form factor and for the ratios	en
