英文摘要The structures of N = 7 isotones have been investigated using the deformed Skyrme-Hartree-Fock model. The approximate particle number projection by means of the Lipkin-Nogami method was used with the blocking effect of the odd neutron taken into account. For nuclei near the drip lines, a volume-surface mixing pairing interaction was employed, which can well reproduce odd-even differences for the long chain of carbon isotopes up to drip lines. The calculated potential-energy curve shows that the first 1/2(+) state of the Be-11 nucleus has a very large prolate deformation. Such a large deformation can result in a good agreement between the calculated and experimental density distribution of the nucleus. The first 1/2(+) state in C-13 is also calculated to have a large deformation, and the 1/2(+) state in He-9 could be a spherical halo attached to a deformed core. The possible halo structure of the 1/2(+) neutron orbit in the N = 7 isotones is discussed. (c) 2005 Elsevier B.V. All rights reserved.
