Low-energy dipole excitation modes in ${}^{10}$Be

Yuki Shikata, Yoshiko Kanada-En'yo, Hiroyuki Morita

Low-energy dipole excitations in ${}^{10}$Be were investigated based on the generator coordinate method with $\alpha +{}^6$He and $\alpha +\alpha +2n$ cluster models. We obtained three $1^{-}$ stat…
