( p,p'. gamma. ) spin-flip measurement for 1/sup +/ states in /sup 12/C at E/sub p/=23. 5--27 MeV

; ; ;
An out-of-plane ( p,p'..gamma..) angular correlation measurement has been made to determine the spin-flip contribution to the ( p,p') cross sections for the 1/sup +/, T=0 (Q=-12.71 MeV) and 1/sup +/, T=1 (Q=-15.11 MeV) excitations in /sup 12/C at proton energies near 27 MeV. A definite isospin dependence is observed in the experimental spin-flip angular distributions for the two states. Microscopic distorted-wave calculations based on a realistic G matrix interaction give a rough account of the trends in the spin-flip data, but underestimate the experimental differential cross sections. It is concluded that reaction contributions calculated in the distorted-wave approximation are insufficient to gain a complete understanding of the data.
