Antisymmetrized molecular dynamics plus Hartree-Fock model and its application to Be isotopes

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 $0^{+}$ state of ${}^{10}\mathrm{Be}.$ The obtained state appears in the vicinity of the lowest $1^{-}$ state. This result is consistent with the experimental data.
