| 英文摘要 | The asymptotic normalization coefficient (ANC) method is used to determine the cross sections of peripheral reaction at astrophysical energies because of existence of the Coulomb barriers. In this paper, we address an estimation of the ANC of B-8 with its single particle wavefunction obtained within the framework of relativistic mean field (RMF) theory. We test the force parameters used in the RMF theory by comparing the calculated structure properties of A = 7-9 drip-line nuclei with experimental results. Utilizing the corrected bound wavefunction of B-8, the ANC C-p3/2(2) = 0.404 is obtained and that indicates the S-17(0) is 18.07 eV b. Additionally, we find that the root-mean-square (rms) radius for loosely bound proton in B-8 is 3.98 fm. This confirms that B-8 has a proton halo structure. |
