Complete Set of Polarization Transfer Observables for the ¹²C(p,n) Reaction at 296 MeV and 0^°

抄録

A complete set of polarization transfer observables has been measured for the ¹²C(p,n) reaction at T_p=296 MeV and θ_lab=0^°. The measured polarization transfer observables indicate that the spin–dipole resonance at E_x\\simeq7 MeV has greater 2⁻ strength than 1⁻ strength, which is consistent with recent experimental and theoretical studies. The total spin transfer Σ(0^°) deduced from the polarization transfer observables indicates a predominance of the spin-flip strength in the continuum. The exchange tensor interaction at a large momentum transfer of Q\\simeq3.6 fm⁻¹ is discussed.
