• 論文の詳細を見る

• The excited states of ^<13>B were studied by a method of antisymmetrized molecular dynamics (AMD). In the excited states, we predicted many cluster states with large deformations that construct the rotational bands, K^π=3/2^- and K^π=1/2^+, starting from 5 and 8MeV, respectively. The neutron structure of the K^π=3/2^- band is analogous to the ^<12>Be ground state with a 2&plank;ω configuration. The K^π=3/2^- -band members correspond to the experimental level at 10.22MeV, which is suggested to be a high-spin state with the 2&plank;ω configuration. In the predicted K^π=1/2^+ band, we found a very exotic molecular structure with a larger deformation than superdeformation. This largely deformed state is dominated by a 3&plank;ω configuration with one proton and two neutrons in the sd shell. In highly excited states, well-developed ^9Li+α cluster structures were predicted.
