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=1927MeV 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.
