Abstract

Resonances in the elastic scattering of ¹⁶O by ¹²C are reported at E_c.m. = 17.29 and 20.79 MeV, with respective J^π assignments of 11⁻ and 13⁻. A 14⁺ spin assignment is shown to be more probable for the resonance at 22.79 MeV than a previous tentative assignment of 16⁺. A correlation is found between maxima of the total fusion cross section and the position of odd angular momentum resonances.

Resonant structures in spin alignment in the 12C+16O inelastic scattering

The spin alignment and cross section have been measured in the ¹²C+¹⁶O inelastic scattering for the ¹²C(g.s.)+¹⁶O(3⁻₁, 6.13 MeV) and ¹²C(2⁺₁, 4.44 MeV)+¹⁶O(g.s.) channels at E_c.m.=17–23 MeV. In both channels, three weakly excited resonant structures are newly observed. Our result of spin alignment in the former channel well reproduces that of the previous study [Phys. Lett. B 120 (1983) 314]. In the latter channel the spin alignment is more or less enhanced at all intermediate structures. The spin alignment data integrated from forward to backward angles in this channel may indicate the presence of gross structure resonances.

Antisymmetrized molecular dynamics: A new insight into the structure of nuclei
2003, Comptes Rendus Physique
The AMD theory for nuclear structure is explained by showing its actual applications. First the formulation of AMD including various refined versions is briefly presented and its characteristics are discussed, putting a stress on its nature as an ab initio theory. Then we demonstrate fruitful applications to various structure problems in stable nuclei, in order to explicitly verify the ab initio nature of AMD, especially the ability to describe both mean-field-type structure and cluster structure. Finally, we show the results of applications of AMD to unstable nuclei, from which we see that AMD is powerful in elucidating and understanding various types of nuclear structure of unstable nuclei.

Cet article présente de la structure de plusieurs noyaux atomiques en utilisant l'approximation de la dynamique moléculaire antisymétrisée (AMD). Après un bref rappel mettant en avant la possibilité de faire des calculs ab initio, nous montrons que cette approche permet de comprendre différents problèmes de structure nucléaire bien connus pour les noyaux stables. En particulier, elle donne une description unifiée des comportements de type champ moyen et de l'apparition d'agrégats de nucléons. Pour finir, nous appliquons AMD aux noyaux instables (exotiques) et nous illustrons qu'une telle approche fournit une explication et une compréhension des différentes structures découvertes avec les noyaux exotiques.

The 8Be + 20Ne molecular resonances in the 12C + 16O collision

Excitation functions of the ¹²C(¹⁶O, ⁸Be)²⁰Ne reaction leading to some low-lying states in ²⁰Ne have been studied at E_c.m. = 22∼29 MeV. Some new resonances are identified with fluctuation analysis, and their spin and parity are determined. If we plot them on a E_c.m. vs. J(J + 1) plane together with resonances reported previously in the same reaction channel, they seem to constitute a rotational band which coincides with the elastic band of the $^{8} Be +^{20} Ne$ system rather than with that of the $^{12} C +^{16} O$ system. Furthermore these resonances are found to persist in having almost negligible correlation in energy with those identified in the $^{12} C +^{16} O$ channels. A resonance at E_c.m. = 26.9 MeV which has been proposed by Eswaran et al. as a superdeformed shape isomeric state is not identified in the present data.
