The electromagnetic decays of the Sigma(0)(1385) and Lambda(1520) hyperons were studied in photon-induced reactions gamma p -> K(+)Lambda(1116)gamma in the Large Acceptance Spectrometer detector at the Thomas Jefferson National Accelerator Facility. We report the first observation of the radiative decay of the Sigma(0)(1385) and a measurement of the Lambda(1520) radiative decay width. For the Sigma(0)(1385)->Lambda(1116)gamma transition, we measured a partial width of 479 +/- 120(stat)(-100)(+81)(sys) keV, larger than all of the existing model predictions. For the Lambda(1520)->Lambda(1116)gamma transition, we obtained a partial width of 167 +/- 43(stat)(-12)(+26)(sys) keV.

We report the first observation of the radiative decay of the Sigma(0)(1385) and a measurement of the Lambda(1520) radiative decay width. For the Sigma(0)(1385)->Lambda(1116)gamma transition, we measured a partial width of 479 +/- 120(stat)(-100)(+81)(sys) keV, larger than all of the existing model predictions. For the Lambda(1520)->Lambda(1116)gamma transition, we obtained a partial width of 167 +/- 43(stat)(-12)(+26)(sys) keV.
