Proton inelastic scattering to the dilute alpha-cluster condensed 0(2)(+) state at E-x=7.654 MeV in C-12
2010
Differential cross sections for the 0 + 2 state at E x = 7.654 MeV in 12 C were measured with the (p,p') reaction at an incident energy of E p = 300 MeV, and in an angular range from θ Lab = 2.7° to 40°. The cross-section data were compared with the distorted-wave Born-approximation calculations employing three types of transition densities obtained in a macroscopic collective model, a microscopic α-cluster model, and a microscopic α-cluster condensation model. It is concluded that the measured angular distribution of the differential cross sections for the 12 C(p,p') reaction at 300 MeV is consistently described with the assumption that the 0 + 2 state at E x = 7.654 MeV is the dilute α-cluster condensed state.
