Abstract: | In order to study the nucleon-nucleon pairing effects in clustering nuclei, we formulate a superposed Tohsaki-Horiuchi- Schuck-Ropke (THSR) wave function, which includes both molecular-orbit and pairing configurations explicitly. With this new wave function, we investigate the anomalous deuteronlike pn-pairing effect in B-10 with T = 0 and S = 1 (isoscalar) by comparing with isovector NN pairs (T = 1, S = 0) in Be-10 and C-10. Energies are calculated for the ground states of Be-10, B-10 and C-10 nuclei, and the 1(1)(+)0 excited state of B-10. These energies are essentially improved comparing with studies using a previous version of THSR wave function. Furthermore, overlaps between the total wave function and the pairing component indicate that the NN pairing effect is more visible in B-10 than in Be-10 and C-10. By analyzing the energies and the overlaps between wave function components, we observe two different mechanisms enhancing the formation of deuteronlike pairs in B-10. We also discuss the pairing effect by showing average distances between components in each nucleus and density distributions of valence nucleons. |
