$2\alpha+t$ cluster structure in $^{11}$B

摘要

The cluster structures of the excited states in 11^{11}B are studied by analyzing the isoscalar monopole and quadrupole strengths in the 11^{11}B(dd,dd') reaction at Ed=200E_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 3/233/2^-_3 state at Ex=8.56E_x=8.56 MeV is well described by the AMD calculation and is an evidence for a developed 2α+t2\alpha+t cluster structure.
