“…In particular, the binding energy and spectrum of exotic proton-excess nucleus 14 F have been predicted [9] in No-core Full Configuration Calculations [7] with the JISP16 N N interaction. These predictions were confirmed in a subsequent experiment [20] where this nucleus was first observed.…”

“…This signal together with a "start" signal from RF of the cyclotron was used for the Time-of-Flight (TF) measurements. This E-T (EnergyTime) combination is used for particle identification in the TTIK approach [16][17][18]. Of course, only α particles should be detected as a result of the interaction of 16 O with helium at the chosen conditions.…”

“…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.

“…The ultimate goal of ab initio studies is to establish a link between underlying principles of quantum chromodynamics (quark/gluon considerations) and observed properties of atomic nuclei, including their structure and related reactions. The predictive potential that ab initio models hold [15,16] makes them suitable for targeting short-lived nuclei that are inaccessible by experiment but essential to modeling, for example, of the dynamics of X-ray bursts and the path of nucleosynthesis (see, e.g., [17,18]). …”

Collective Modes in Light Nuclei from First Principles

et al. 2013

Results for ab initio no-core shell model calculations in a symmetry-adapted SU(3)-based coupling scheme demonstrate that collective modes in light nuclei emerge from first principles. The low-lying states of 6 Li, 8 Be, and 6 He are shown to exhibit orderly patterns that favor spatial configurations with strong quadrupole deformation and complementary low intrinsic spin values, a picture that is consistent with the nuclear symplectic model. The results also suggest a pragmatic path forward to accommodate deformation-driven collective features in ab initio analyses when they dominate the nuclear landscape.Introduction. -Major progress in the development of realistic inter-nucleon interactions along with the utilization of massively parallel computing resources [1][2][3] have placed ab initio approaches [4][5][6][7][8][9][10][11][12][13][14] at the frontier of nuclear structure explorations. The ultimate goal of ab initio studies is to establish a link between underlying principles of quantum chromodynamics (quark/gluon considerations) and observed properties of atomic nuclei, including their structure and related reactions. The predictive potential that ab initio models hold [15,16] makes them suitable for targeting short-lived nuclei that are inaccessible by experiment but essential to modeling, for example, of the dynamics of X-ray bursts and the path of nucleosynthesis (see, e.g., [17,18]).
