CNPC2023近球形核94Nb的高自旋态研究
High-spin states in near stable nucleus 94Nb
通过重离子熔合蒸发反应82Se(18O，p5n)94Nb，布居了94Nb的高自旋态，实验中使用的18O束流由中国原子能科学研究院的HI-13串列加速器提供，束流能量为82MeV和88MeV。在前人工作的基础上发现了15条新的γ跃迁并调整了部分能级的摆放位置，丰富并完善了94Nb的能级纲图，结合DC0比值和线极化测量，确认了部分能级的自旋和宇称。在质子π(1f5/2, 2p3/2, 2p1/2, 1g9/2)和中子ν(2p1/2, 1g9/2, 1g7/2, 2d5/2)空间下对94Nb新的能级结构与壳模型计算进行了比较和讨论。

High spin states of 94Nb have been studied with the 82Se(18O, p5n)94Nb fusion evaporation reaction at anincident beam energy of 82and 88 MeV. The level scheme of 94Nbhas been modified and extended with 15 newγrays. Based on γ-γcoincidence relationshipsDCO ratios and linear polarization measurements, the new level structures in 94Nb have been interpreted in terms of the shell model calculations performed in the configuration space π(1f5/2, 2p3/2, 2p1/2, 1g9/2 ) for the protons and ν(2p1/2, 1g9/2, 1g7/2, 2d5/2 ) for the neutrons.
