“…Indeed, radioactive nuclei cannot be used as a target, and rare beams cannot be used to study a broad energy region with good energy resolution using small controlled changes of the energy as it was in conventional measurements. The first work to study alpha cluster states in N Z nuclei using 18 Ne rare beam (and a comparison with the 18 O data) was made using a novel Thick Target Inverse Kinematics (TTIK) method [3] in collaboration with Prof. Spitaleri's group [4]. It showed exciting and unexpected differences in the excitation functions of mirror reactions 18 O(α,α) and 18 Ne(α,α).…”

“…From an experimental perspective, the aim of this work is to obtain new information on the structure of 20 like other experimentalists, we used the Thick Target Inverse Kinematics method (TTIK) (see [15][16][17][18][19] and references therein) to study the excitation functions for the 16 O(α,α) 16 O elastic scattering in the 20 Ne excitation region of 5.5 − 9.6 MeV and in a broad angular interval. On the theoretical side, we also used multi configuration shell model calculations to understand the limits of this approach in the description of the cluster states.…”

Background: The nuclear structure of the cluster bands in 20 Ne presents a challenge for many theoretical approaches. It is especially difficult to explain the broad 0 + and 2 + states, both at around 9 MeV excitation energy. More reliable experimental data for these levels is important for proper quantitative assessment and development of theoretical methods.Purpose: To obtain new data on 20 Ne α-cluster structure.Method: Thick target inverse kinematics technique was used to study the 16 O+α resonance elastic scattering and the data were analyzed using an R-matrix approach. The 20 Ne spectrum, the cluster and nucleon spectroscopic factors were calculated using cluster-nucleon configuration interaction model (CNCIM). Conclusions: Our experimental results obtained by the TTIK method generally confirm the adopted data on α cluster levels in 20 Ne. The CNCIM gives a good description of the 20 Ne positive parity states up to an excitation energy of ∼ 7 MeV, predicting reasonably well the excitation energy of the states and their cluster and single particle properties. At higher excitations, a qualitative disagreement with the experimentally observed structure is evident, especially for broad resonances.

“…Moreover, two α cluster bands (α 2 + and α 0 + ) with α-24 Mg cluster structure are found in high excited states. As for the experimental α 0 + band, averaged values of the excitation energy are listed because those states are fragmented (dotted lines) [14].…”

Abstract.We have studied positive-parity states of 28 Si using antisymmetrized molecular dynamics and multiconfiguration mixing with constrained variation. Applying constraints to the cluster distance and the quadrupole deformation of the variational calculation, we have obtained basis wave functions that have various structures such as α-24 Mg and 12 C-16 O cluster structures as well as deformed structures. Superposing those basis wave functions, we have obtained a oblate ground state band, a β vibration band, a normal-deformed prolate band, and a superdeformed band. It is found that the superdeformed bands contain large amounts of the α-24 Mg cluster components. The results also suggest the presence of two excited bands with the developed α-24 Mg cluster structure, where the inter-cluster motion and the 24 Mg-cluster deformation play important roles.
