Abstract

A complete set of polarization transfer observables has been measured for the 90Zr(p, n) reaction at Tp = 295 MeV and θlab = 0inverted c sign. The measurement can yield the total spin transfer Σ(0inverted c sign) which is independent of nuclear reaction mechanisms such as the effective nucleon-nucleon interaction or distortions. The deduced Σ(0inverted 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.
