论文摘要
三重变形核的集体旋转的有效场理论通过将价核的角动量作为额外的自由度推广到奇数核中。在有效的领域理论形式主义中，哈密顿人建成的临近秩序。通过描述在Lutetium同位素中观察到的摇摆带$^{{161,163,165,167} $ LU中观察到的摇摆带来检查该哈密顿量的适用性。发现，通过考虑到近距离领先的订单校正，在转子角动量中四分之一的矫正，摇摆能的能量$ e _ {\ textrm {wob}} $和自旋 - 转移频率关系$ω（i）$的描述更好地描述了吉尔顿的领先顺序。
The effective field theory for collective rotations of triaxially deformed nuclei is generalized to odd-mass nuclei by including the angular momentum of the valence nucleon as an additional degree of freedom. The Hamiltonian is constructed up to next-to-leading order within the effective field theory formalism. The applicability of this Hamiltonian is examined by describing the wobbling bands observed in the lutetium isotopes $^{161,163,165,167}$Lu. It is found that by taking into account the next-to-leading order corrections, quartic in the rotor angular momentum, the wobbling energies $E_{\textrm{wob}}$ and spin-rotational frequency relations $ω(I)$ are better described than with the leading order Hamiltonian.
