    "abstract": "A short overview of motivations and successes of two-body exchange currents\nbetween constituent quarks for electromagnetic hadron observables like charge\nradii, magnetic and quadrupole moments is given. We then predict and analyze\nexchange current effects on the radiative decay widths of decuplet hyperons,\nwhich are to be measured soon. In our chiral constituent quark model, exchange\ncurrents dominate the E2 transition amplitude, while they largely cancel for\nthe M1 transition amplitude. Strangeness suppression of the radiative hyperon\ndecays is weakened by exchange currents. The SU(F)_3 flavor symmetry breaking\nfor the negatively charged hyperons is strong.",
