    "abstract": "Radiative decays of decuplet hyperons and octet hyperon charge radii are\nevaluated in a chiral constituent quark model emphasizing the role of exchange\ncurrents. Exchange currents largely cancel for the M1 decay amplitudes, while\nthey dominate the E2 amplitude. Due to the pseudoscalar meson cloud the charge\nradii of Sigma^- and Xi^- are almost as large as the proton radius, in\nagreement with recent experimental results from SELEX. Strangeness suppression\nis weakened by exchange currents for several observables.",
