A recently developed non-perturbative chiral approach to dynamically generatethe (3/2^-) baryon resonances has been extended to investigate the radiativedecays Lambda^*(1520) --> gamma Lambda(1116) and Lambda^*(1520) --> gammaSigma^0(1193). We show that the Lambda^*(1520) decay into gamma Lambda is anideal test for the need of extra components of the resonance beyond thoseprovided by the chiral approach since the largest meson-baryon components giveno contribution to this decay. The case is different for gamma Sigma decaywhere the theory agrees with experiment, though the large uncertainties ofthese data call for more precise measurements.Comment: 15 pages, 6 figure
