Abstract

Cross Sections and polarization transfer observables in the 16O(p,p′) reactions at 392 MeV were measured at several angles between θlab =0° and 14°. The non-spin-flip (ΔS = 0) and spin-flip (ΔS = 1) strengths in transitions to several discrete States and broad resonances in 16O were extracted using a model-independent method. The giant resonances in the energy region of Ex = 19-27 MeV were found to be predominantly excited by ΔL = 1 transitions. The strength distribution of spin-dipole transitions with ΔS = 1 and ΔL = 1 were deduced. The obtained distribution was compared with a recent shell model calculation. Experimental results are reasonably explained by distorted-wave impulse-approximation calculations with the shell model wave functions.
