The cluster structures of the excited states in <sup>11</sup>B are studied by analyzing the isoscalar monopole and quadrupole strengths in the <sup>11</sup>B(d, d′) reaction at E<sub>d</sub> 200 MeV. The excitation strengths are compared with the theoretical predictions by the antisymmetrized molecular-dynamics (AMD) calculations. It is found that the large monopole strength for the 3/2<sup>−</sup><sub>3</sub> state at E<sub>x</sub> 8.56 MeV is well described by the AMD wave function with a dilute 2α + tcluster structure.
