用实时演化方法(REM)研究了具有++价中子团簇结构的Be同位素。通过求解包含复杂空间坐标和自旋变量的高斯波波包的运动方程，得到了各种分子构型，并将其叠加到生成器坐标方法(GCM)中。从Be同位素得到的能谱比其他团簇模型的能谱更好，也与实验基本一致。结果表明，实时演化方法为我们提供了一种选择基波函数来处理Be同位素多中子分子结构的有效方法。
The Be isotopes with++ valence neutrons clustering structure are studied within the Real-time Evolution Method (REM). By solving the equation-of-motion (EOM) of the Gaussian wave packets involving the complex spatial coordinates and spin variables, various molecular configurations are obtained and then are superposed in the Generator Coordinate Method (GCM). The obtained energy spectra from Be isotopes are better than those from other cluster models and also basically consistent with experiments. It is found the real-time evolution method provides us with an effective way to choose basis wave functions for dealing with the multi-neutron molecular structures of Be isotopes.
