“…8 Be is well-known for the α-α clustering structure with an elongated prolate shape. Valence neutrons added to 8 Be are expected to cause variety of structure change in the ground and excited states [73,74,75]. 10 Be has two neutrons in addition to 8 Be.…”

Linear response theory in the continuum for deformed nuclei: Green's function vs time-dependent Hartree-Fock with the absorbing boundary condition

The continuum random-phase approximation is extended to the one applicable to deformed nuclei. We propose two different approaches. One is based on the use of the three dimensional (3D) Green's function and the other is the small-amplitude TDHF with the absorbing-boundary condition. Both methods are based on the 3D Cartesian grid representation and applicable to systems without any symmetry on nuclear shape. The accuracy and identity of these two methods are examined with the BKN interaction. Using the full Skyrme energy functional in the small-amplitude TDHF approach, we study the isovector giant dipole states in the continuum for 16 O and for even-even Be isotopes.

“…Since the normal forms of these nuclei have a variety of structures, such as a coexistence of shell and cluster structure [14][15][16] and novel exotic clustering [17][18][19][20][21], there must be many interesting phenomena peculiar to hypernuclei to be found. Indeed, several pioneering works have predicted exotic structures in sd-shell hypernuclei, such as parity inversion in 20 Ne [7] and various rotational bands in 21 Ne [22].…”

“…To perform such a systematic and quantitative study of sd-shell and neutron-rich hypernuclei, we have developed an extended version of antisymmetrized molecular dynamics (AMD) [18,[28][29][30][31], which we shall call HyperAMD. AMD has been successful at describing various exotic structures of neutron-rich nuclei and highly excited states of stable nuclei.…”

Deformation of hypernuclei studied with antisymmetrized molecular dynamics

An extended version of antisymmetrized molecular dynamics was developed to study the structure of p-sd shell hypernuclei. By using an effective N interaction, we investigated the energy curves of 9 Be, 13 C, and 20,21 Ne as a function of nuclear quadrupole deformation. The changes to nuclear deformation caused by particles are discussed. We found that in the p wave enhances nuclear deformation, while that in the s wave reduces it. This effect is most prominent in 13 C. The possibility of parity inversion in 20 Ne is also examined.

“…A variational method called AMD (antisymmetrized molecular dynamics) [30,31] A problem common to the above two works is that within the quark models one cannot predict the absolute masses but only the level structure of the pentaquarks in principle.…”

We study IJ P = 0 3 2 ± and 1 3 2 ± pentaquark states with S = +1 in the QCD sum rule approach.The QCD sum rule for positive parity states and that for negative parity are independently derived.The sum rule suggests that there exist the 0 3 2 − and the 1 3 2 − states. These states may be observed as extremely narrow peaks since they can be much below the S-wave threshold and since the only allowed decay channels are N K in D-wave, whose centrifugal barriers are so large that the widths are strongly suppressed. The 0 3 2 − state may be assigned to the observed Θ + (1540) and the 1 3 2 − state can be a candidate for Θ ++ .
