标题： 1/N expansion formalism for high-spin states

摘要： 1/$N$展开解对于相互作用玻色子模型被使用计算机代数扩展到更高阶。 分析结果与从哈密顿量精确对角化得到的结果进行比较，显示出非常准确。 能级和E2跃迁的扩展公式在分析正常核和超形变核中的高自旋态时将是有用的。 显示英文摘要

摘要： The 1/$N$ expansion solutions for the interacting boson model are extended to higher orders using computer algebra. The analytic results are compared with those obtained from an exact diagonalization of the Hamiltonian and are shown to be very accurate. The extended formulas for level energies and E2 transitions will be useful in the analysis of high-spin states in both normal and superdeformed nuclei.
