As part of an NSF-JSPS Collaborative Research Project (JJ&MF), giant resonances up to E{sub x} {approximately} MeV in {sup 90}Nb have been studied with a 450-MeV {sup 3}He beam from the RCNP Ring Cyclotron. Tritons from ({sup 3}He,t) were observed at 0=0{degrees} with the K=1400 magnetic spectrometer Grand Raiden in coincidence with decay protons detected in eight SiLi detectors close to the target. Competition between {gamma}, proton-, and neutron-emission affects the observed shape of the T=4 main Gamow-Teller resonance (GTR). The T=4 and T=5 GTR`s and the spin-dipole resonance decay mostly to low-lying states in {sup 89}Zr. Second-chance proton emission is also observed.
