The differential cross-sections of the elastic and inelastic [Formula: see text]C scattering have been measured at E[Formula: see text][Formula: see text]MeV. The radii of the exited states: 3.09 [Formula: see text] and 8.86 [Formula: see text] MeV were determined using the Modified Diffraction Model. The radii of these excited states are larger than that of the ground state of [Formula: see text]C, confirming the suggestion that the 8.86 [Formula: see text] MeV state could be an analog of the Hoyle state in [Formula: see text]C and the 3.09 [Formula: see text] MeV state has a neutron halo. The possibility of coexistence of various exotic states in the structure of the [Formula: see text]C nucleus is shown.

Diffraction Model

The differential cross-sections of the elastic and inelastic α +11B scattering was measured at E(α) = 29 MeV. The analysis of the data by Modified Diffraction Model (MDM) showed that the root-mean- square (RMS) radius of the 11B state 3/2-, E* = 8.56 MeV is ~ 0.5 fm larger than that of the ground state. It is found that the radius of 3/2- (8.56 MeV) state in the 11B nucleus is close to the radii of the Hoyle state in 12C.

Good Agreement

We have used the nonrelativistic convergent close-coupling (CCC) method to investigate electron scattering from the ground (6s2)1S state and excited (6s6p)1 Po1 and (6s5d)1,3De2 states of barium. For the scattering from the barium ground state, we have found very good agreement with measurements of (6s6p)1 Po1 apparent cross sections at all energies. Similarly, good agreement is found for differential cross sections for elastic scattering and (6s6p)1 Po and (6s5d)1 De2 excitations and with the (6s6p)1 Po1 state electron{photon angular correlations. For the scattering from excited states of barium we have found good agreement with elastic (6s6p)1 Po1 scattering and the (6s5d)1De2 → (6s6p)1 Po1 transition for both differential cross sections and electron–photon angular correlations.

Angular distributions of the differential cross sections and analysing powers were measured at an energy of 4.6 MeV. The results are compared with the distorted wave Born approximation predictions for two-nucleon transfer and for a deuteron-cluster transfer. The agreement is qualitative at best, and a discussion of alternatives to improve it is presented.
