“…Thus the radii of 12 B in the halo states that will be presented in this paper are useful in estimating the radii of the nuclei with A = 12 determined by other methods. It should be mentioned in this connection that a possibility to apply the modified diffraction method (MDM) [34][35][36] for determining the radii of nuclei in the excited states by studying the charge-exchange ( 3 He, t ) reactions was recently proposed [37]. The first applications of MDM to the mirror states of 13 C and 13 N nuclei [37] have demonstrated the effectiveness of this new approach.…”

“…The COP is utilized in the OM calculations of 4 He+ 12 C at other energies as well to analyze the applicable energy range. Using the COP in the reaction at 27.5 A MeV [26], the experimental ESAD is reproduced successfully as those data sets in Fig. 1.…”

A common optical potential for 4 He+ 12 C at intermediate bombarding energies, which is essential in analyzing exotic nuclei with 4 He clusters, was obtained based on the São Paulo potential (SPP). Among systematic optical potentials for 4 He+ 12 C, this potential has the merit of using a fixed imaginary part of Woods-Saxon form. By optical-model calculations, this potential reproduced the experimental elastic scattering angular distributions of 4 He+ 12 C well within the energy range of 26 A-60 A MeV. It was also applied successfully in calculations of the breakup reactions of 6 Li+ 12 C and 6 He+ 12 C with a three-body continuum discretized coupled-channels method.

“…The overall energy resolution was about 200 keV due to use of a beam monochromatization system. Besides, we reconstructed the cross-section of the inelastic scattering cross-section to the state 4 + , 14.08 MeV from the data measured at 110 MeV previously [11] but unpublished at that time.…”

Abstract. α + 12 C inelastic differential cross-sections were measured at the energies 65 and 110 MeV. A new broad state at 13.75 MeV was observed. Its spin-parity has been determined as 4 + and the diffraction radius of the corresponding L = 4 transition is ~ 0.8 fm larger than that of the excitation of the 4+, 14.8 MeV level. The 13.75 MeV state was considered to be the third member of the rotational band based on the Hoyle state.
