nonlocalized Clustering a new concept in nuclear Cluster Structure physics
Physical Review Letters, 2013Co-Authors: Hisashi Horiuchi, B. Zhou, Y. Funaki, G. Röpke, P. Schuck, Zhongzhou Ren, A. TohsakiAbstract:We investigate the $\ensuremath{\alpha}+^{16}\mathrm{O}$ Cluster Structure in the inversion-doublet band (${K}^{\ensuremath{\pi}}={0}_{1}^{\ifmmode\pm\else\textpm\fi{}}$) states of $^{20}\mathrm{Ne}$ with an angular-momentum-projected version of the Tohsaki-Horiuchi-Schuck-R\"opke (THSR) wave function, which was successful ``in its original form'' for the description of, e.g., the famous Hoyle state. In contrast with the traditional view on Clusters as localized objects, especially in inversion doublets, we find that these single THSR wave functions, which are based on the concept of nonlocalized Clustering, can well describe the ${K}^{\ensuremath{\pi}}={0}_{1}^{\ensuremath{-}}$ band and the ${K}^{\ensuremath{\pi}}={0}_{1}^{+}$ band. For instance, they have 99.98% and 99.87% squared overlaps for ${1}^{\ensuremath{-}}$ and ${3}^{\ensuremath{-}}$ states (99.29%, 98.79%, and 97.75% for ${0}^{+}$, ${2}^{+}$, and ${4}^{+}$ states), respectively, with the corresponding exact solution of the $\ensuremath{\alpha}+^{16}\mathrm{O}$ resonating group method. These astounding results shed a completely new light on the physics of low energy nuclear Cluster states in nuclei: The Clusters are nonlocalized and move around in the whole nuclear volume, only avoiding mutual overlap due to the Pauli blocking effect.

Nonlocalized Clustering: A New Concept in Nuclear Cluster Structure Physics
Physical Review Letters, 2013Co-Authors: B. Zhou, Y. Funaki, H. Horiuchi, Zhuoxiang Ren, G. Röpke, P. Schuck, A. Tohsaki, T. YamadaAbstract:We investigate the α+16O Cluster Structure in the inversion-doublet band (Kπ=01±) states of 20Ne with an angular-momentum-projected version of the Tohsaki-Horiuchi-Schuck-Röpke (THSR) wave function, which was successful "in its original form" for the description of, e.g., the famous Hoyle state. In contrast with the traditional view on Clusters as localized objects, especially in inversion doublets, we find that these single THSR wave functions, which are based on the concept of nonlocalized Clustering, can well describe the Kπ=01- band and the Kπ=01+ band. For instance, they have 99.98% and 99.87% squared overlaps for 1- and 3- states (99.29%, 98.79%, and 97.75% for 0+, 2+, and 4+ states), respectively, with the corresponding exact solution of the α+16O resonating group method. These astounding results shed a completely new light on the physics of low energy nuclear Cluster states in nuclei: The Clusters are nonlocalized and move around in the whole nuclear volume, only avoiding mutual overlap due to the Pauli blocking effect.

Coexistence of Cluster Structure and mean-field-type Structure in medium-weight nuclei
Nuclear Physics, 2006Co-Authors: Yasutaka Taniguchi, Yoshiko Kanada-en'yo, Masaaki Kimura, Hisashi HoriuchiAbstract:We have studied the coexistence of Cluster Structure and mean-field-type Structure in 40 Ca using Antisymmetrized Molecular Dynamics (AMD) + Generator Coordinate Method (GCM). By energy variation with constraint, we calculated GCM basis wave functions. Superposing Cluster Structure wave functions and mean-field-type Structure wave function, we found that α - 36 Ar and 12 C- 28 Si Cluster Structure are important components of normal-deformed (ND) band of 40 Ca and that of superdeformed (SD) band of 40 Ca, respectively.

AIP Conference Proceedings, 2006Co-Authors: Yasutaka Taniguchi, Masaaki Kimura, Hisashi HoriuchiAbstract:We have studied the coexistence of Cluster Structure and mean‐field‐type Structure in 20Ne and 40Ca using Antisymmetrized Molecular Dynamics (AMD) + Generator Coordinate Method (GCM). By energy variation with new constraint for Clustering, we calculate Cluster Structure wave function. Superposing Cluster Structure wave functions and mean‐field‐type Structure wave function, we found that 8Be‐12C, α‐36Ar and 12C‐28Si Cluster Structure are important components of Kπ = 03+ band of 20Ne, that of normal deformed band of 40Ca and that of super deformed band of 40Ca, respectively.

Coexistence of Cluster Structure and superdeformation in 44Ti
Nuclear Physics A, 2006Co-Authors: Masaaki Kimura, Hisashi HoriuchiAbstract:Abstract The nucleus 44Ti has low-lying levels of various kinds of mutually very different nuclear Structure displaying the richness of the nuclear many-body dynamics. It is shown that the deformed-basis antisymmetrized molecular dynamics by the use of the Gogny D1S force reproduces successfully and unifiedly two types of coexistence phenomena in 44Ti. Namely, on one hand, the coexistence of the mean-field Structure and the Cluster Structure is confirmed by verifying the normally deformed Structure of the K π = 3 1 − band with a 1-particle–1-hole intrinsic configuration and the α + Ca 40 Cluster Structure of the K π = 0 2 − band. The mixed character of the mean-field-like Structure and the α + Ca 40 Cluster Structure of the ground band is also shown. On the other hand, the coexistence of the normal deformed mean-field and the superdeformed mean-field is confirmed by verifying the triaxial superdeformation of the K π = 0 2 + band and the K π = 2 1 + band which has a 4-particle–4-hole intrinsic configuration. Good reproduction of the experimental data is shown for many kinds of quantities including the energy spectra, electric transition rates, alpha spectroscopic factors. Preliminary discussions are given on the existence of hyperdeformed excited states, the relation between superdeformation and Clustering and so on.

Cluster Structure in stable and unstable nuclei
European Physical Journal A, 2005Co-Authors: Yoshiko Kanada-en'yo, Masaaki Kimura, Hisashi HoriuchiAbstract:Cluster Structure in stable and unstable nuclei has been studied. We report recent developments of theoretical studies on Cluster aspect, which is essential for Structure study of light unstable nuclei. We discuss negative-parity bands in even-even Be and Ne isotopes and show the importance of Cluster aspect. Three-body Cluster Structure and Cluster crystallization are also introduced. It was found that the coexistence of Cluster and mean-field aspect brings a variety of Structures to unstable nuclei.
