为了系统地研究轻不稳定核，我们提出了一种新的方法--反对称化分子动力学加Hartree-Fock（AMD+HF）方法。这种方法将单粒子轨道的概念引入到通常的AMD中。将AMD+HF方法应用于Be同位素，计算得到的最低本征态的正负宇称与双中心壳层模型的解释有较好的一致性。此外，我们还积极利用从AMD波函数中提取的单粒子轨道，构造了{sup 10}Be的第一激发0{sup +}态。所获得的状态出现在最低的1{sup {minus}}状态附近。这一结果与实验数据一致。{版权} {美国物理学会}
In order to study light unstable nuclei systematically, we propose a new method, the antisymmetrized molecular dynamics plus Hartree-Fock (AMD+HF) method. This method introduces the concept of the single particle orbits into the usual AMD. Applying the AMD+HF method to Be isotopes, it is found that the calculated lowest intrinsic states with plus and minus parities have rather good correspondence with the explanation by the two-center shell model. In addition, by active use of the single particle orbits extracted from the AMD wave function, we construct the first excited 0{sup +} state of {sup 10}Be. The obtained state appears in the vicinity of the lowest 1{sup {minus}} state. This result is consistent with the experimental data. {copyright} {ital 1997} {ital The American Physical Society}
