Abstract

The Be isotopes with \(\alpha \) + \(\alpha \) + 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.
