Abstract

We report measurements of cross sections and analyzing powers for reaction angles of θlab = 0.0°-10.0° and complete sets of polarization transfer observables and induced polarizations at θlab = 0.0°-7.0° for the 208Pb(p,n) reaction at a bombarding energy of Tp = 296 MeV. A multipole decomposition technique was applied to the data to extract the spin-dipole (SD) components from the continuum. The polarization observables were also used, for the first time, to separate the SD components into different spin-parity transfer (ΔJπ = 0-, 1-, and 2-) contributions. The SD strength distributions were clearly dependent on ΔJπ, which is reasonably reproduced by Hartree-Fock (HF) plus random phase approximation (RPA) calculations that include the Skyrme interaction with tensor components [C. L. Bai et al., Phys. Rev. C 83, 054316 (2011)].
