چکیده

The low-lying states of light nuclei He and Be are studied in this letter. With the inherent nodal surface(INS) analysis approach, the quantum numbers and the spatial symmetries of the low-lying states with positive parity and negative parity of the two nuclei are deduced. The obtained energy spectrum structure agrees with experimental data well.

Low-Lying States of He and Be in a Nodal Surface Structure Analysis

The low-lying states of the light nuclei He and Be are studied. Using the inherent nodal surface(INS) analysis approach, we deduce the quantum numbers and the spatial symmetries of the low-lying states with positive parity and negative parity of the two nuclei. The energy spectrum obtained agrees well with the experimental

Low-lying S-wave and P-wave Dibaryons in a Nodal Structure Analysis

The inherent nodal surface structure analysis approach is proposed for the sixquark clusters with u, d and s quarks. The wave-functions of the six-quark clusters are classified, and the contribution of the hidden-color channels are discussed. The quantum numbers and configurations of the wave-functions of the low-lying dibaryons are obtained. The states [ΩΩ](0,0+), [ΩΩ](0,2−), [Ξ ∗Ω](1/2,0+), [...

Nodal Structure Analysis

The strangeness s = +1 pentaquark states as qqqqq̄ clusters are investigated in this letter. Starting from the inherent geometric symmetry, we analyzed the inherent nodal structure of the system. As the nodeless states, the low-lying states are picked out. Then the S-wave state (J , T ) = (12 − , 0) and P-wave state (J , T ) = (12 + , 0) may be the candidates of low-lying pentaquark states. By c...

Deduction of the Quantum Numbers of Low-lying States of 4-nucleon Systems Based on Symmetry

The inherent nodal structures of the wavefunctions of 4-nucleon systems have been investigated. The existence of two groups of low-lying states with specific quantum numbers dominated by total orbital angular momentum L=0 and L=1, respectively, has been deduced. The understanding of the inherent nodal structure is found to be crucial to a systematic understanding of the spectrum. PACS: 21.45.+v...

Effects of on-center impurity on energy levels of low-lying states in concentric double quantum rings

In this paper, the electronic eigenstates and energy spectra of single and two-interacting electrons confined in a concentric double quantum rings with a perpendicular magnetic field in the presence of         on-center donor and acceptor impurities are calculated using the exact diagonalization method. For a single electron case, the binding energy of on-center donor and acceptor impurities ar...
