Evidence for α‐cluster condensation in the 02+ state at Ex = 7.654 MeV in 12C via the (p,p′) reaction at 300 MeV

We measured the differential cross sections for the 02+ state at Ex = 7.654 MeV in 12C via the (p,p′) reaction at an incident energy of 300 MeV, and in an angular range from 2.7° to 40°. We analyzed the data with the distorted‐wave Born‐approximation (DWBA) employing 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 present results for the 12C(p,p′) reaction at 300 MeV is quite consistent with the assumption that the 02+ state at Ex = 7.654 MeV has the wave function with the α‐cluster condensation.We measured the differential cross sections for the 02+ state at Ex = 7.654 MeV in 12C via the (p,p′) reaction at an incident energy of 300 MeV, and in an angular range from 2.7° to 40°.
