Abstract

A complete set of polarization transfer observables has been measured for the ⁹⁰Zr(p, n) reaction at T_p = 295 MeV and θ_lab = 0^{inverted c sign}. The measurement can yield the total spin transfer Σ(0^{inverted c sign}) which is independent of nuclear reaction mechanisms such as the effective nucleon-nucleon interaction or distortions. The deduced Σ(0^{inverted c sign}) values indicate the strong spin-flip characteristics of the continuum up to 50 MeV excitation. A predominance of unnatural-parity transitions in the continuum is also observed from polarization transfer observables.
