论文摘要
探索了一种从核密度功能开始的光谱的方法。这个想法是基于假设有效的哈密顿量，该汉密尔顿人重现了与集体模式相关的刚度。该方法定义了这种有效的哈密顿量和映射的简单形式，从密度功能转向相应的哈密顿量。为了测试该方法，使用Skyrme功能来限制Hamiltonian，并使用发电机坐标方法求解，以描述$^{48,49,50,52} $ CR和$^{24} $ Mg中的低洼水平和电磁过渡。
A method to describe spectra starting from nuclear density functionals is explored. The idea is based on postulating an effective Hamiltonian that reproduces the stiffness associated with collective modes. The method defines a simple form of such an effective Hamiltonian and a mapping to go from a density functional to the corresponding Hamiltonian. In order to test the method, the Hamiltonian is constrained using a Skyrme functional and solved with the generator-coordinate method to describe low-lying levels and electromagnetic transitions in $^{48,49,50,52}$Cr and $^{24}$Mg.
