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 Ed = 200   MeV. The excitation strengths are compared with the predictions by the shell-model and antisymmetrized molecular-dynamics (AMD) calculations. The large monopole strength for the 3 / 23- state at Ex = 8.56   MeV is well described by the AMD calculation and is suggested to be an evidence for a well developed 2 α + t cluster structure.
