摘要：
Gamow-Teller (GT) transitions in beta decays of Li-9 and Li-11 are investigated with theoretical calculations of antisymmetrized molecular dynamics. The calculated B(GT) values are small for transitions to low-lying states in Be isotopes, whereas relatively large B(GT) values are found for excited states at excitation energy E-x >= 10 MeV. The sum of the B(GT) values is discussed for each spin-parity of final states. The calculated results seem to be inconsistent with an experimental report of the strongest GT transition from Li-9 to the 5/2(-) state of Be-9 at 11.8 MeV.
