摘要: The chiral interpretation of negative-parity twin bands in the odd-$A$ $^{135}\mathrm{Nd}$ nucleus was investigated interacting boson-fermion model. IBFM calculation shows that dominant role formation pattern has exchange interaction, i.e., antisymmetrization odd fermions with fermion structure bosons. $^{137}\mathrm{Nd}$ also been investigated, concluding it is determined by shape fluctuations and prolate-oblate coexistence rather than chirality.
