Abstract

The cluster structures of the excited states in ¹¹B are studied by analyzing the isoscalar monopole and quadrupole strengths in the ¹¹B(d,d′) reaction at E_d = 200 MeV. The excitation strengths are compared with the predictions by the shell-model and antisymmetrized molecular-dynamics (AMD) calculations. It is found that the large monopole strength for the 3/2₃^- state at E _x = 8.56 MeV is well described by the AMD calculation and is an evidence for a developed 2α + t cluster structure.
