E2 M1 RATIO FOR THE GAMMA-N-]DELTA TRANSITION IN THE CHIRAL QUARK SOLITON MODEL/

We calculate the electric quadrupole to magnetic dipole transition rat io E2/M1 for the reaction gamma N --> Delta(1232) in the chiral quark soliton model. The calculated E2/M1 ratio is in a good agreement with the very new experimental data. We obtain non-zero negative value for the electric quadrupole N - Delta transition moment, which suggests an oblate deformed charge structure of the nucleon or/and the delta isob ar. Other observables related to this quantity, namely the N - Delta m ass splitting, the isovector charge radius, and isovector magnetic mom ent, are properly reproduced as well.
