摘要: 通过重离子熔合蒸发反应¹¹⁶Cd(²⁷Al， 4n)布居了¹³⁹Pm的高自旋激发态，用12台高纯锗探测器（HpGe）阵列进行了在束γ-γ 符合测量。基于γ-γ符合关系及¹³⁹Pm核已知的能级信息，建立了两条ΔI=1的负宇称带。利用相邻核能级结构的系统性和依据半经典的核子-核子有效作用的理论模型（SPAC）对这两条带能级结构进行了定量计算，认为它们属于磁转动带。 Highspin states in ¹³⁹Pm have been studied via the¹¹⁶Cd(²⁷Al， 4n) heavyion fusionevaporation reaction. The γ-γ coincidences were measured with 12 HpGe detectors. Based on γ-γ coincidence relationships and previously known levels in ¹³⁹Pm， two ΔI＝1 negativeparity bands have been established. From the systematic comparison with the neighbouring nuclei and semiclassical effective interaction model (SPAC) calculations， the two bands were suggested as magnetic rotational bands.
