The study of particle decay of charge-exchange giant resonances (CEGR) furnishes information on their microscopic structure. Furthermore, gamma decay of CEGR call help to unravel their structure. For example, the gamma-decay of the Gamow-Teller (GT) resonance to the isobaric analogue state (IAS) points to a possible method to study quenching of GT strength. The study of gamma-decay of the spin-flip dipole resonance (SDR) to GT and low-lying states will possibly allow to disentangle the different spin components. These aspects will be discussed in the light of recent (He-3,t) experiments at E(He-3) = 450 MeV and theta = 0 degrees performed to study the proton decay of CEGR in Bi-208 and N-12 and the gamma decay of the GT resonance, IAS and SDR in Nb-90.</p
