Differential cross sections at θ_lab = 0.0°- 12.3° and a complete set of polarization transfer observables at θ_lab = 0.0° are measured for the ⁹⁰Zr(p, n) reaction at T_p = 295 MeV. A multipole decomposition analysis (MDA) technique is applied to the cross sections to deduce the Gamow-Teller (GT) strength B(GT). The obtained S_β- = ∑ B(GT) value is 28.0 ± 1.6. The total spin transfer ∑ is obtained for the continuum by using polarization transfer measurements. The S_β- - S_β+ value is deduced to be 27.0 and this is 90% of Ikeda's sum rule value of 3(N - Z)=30. Thus the quenching of the GT strength is small and the quenching mechanism due to the ΔN^- admixture seems to play a minor role.
