【摘要】 利用122.5MeV19F束流,通过142Nd(19F,5n)156Tm熔合蒸发反应布居了156Tm核的高自旋态,测量了γ-γ符合及DCO比值,建立了一个有29条能级,33条γ跃迁的能级纲图.新增加了20条γ跃迁,18条能级.将能级自旋推高到(34-).更多还原

【Abstract】 The high spin states of 156 Tm were populated using fusion evaporation 142Nd(19F, 5n)156Tm reaction at beam energy of 122.5MeV. The γ-γ coincidence and DCO ratios were measured with 13 HPGe-BGO detectors. A level scheme with 29 levels and 33 γ-transitions was proposed. About 18 levels and 20 γ-transitions were added to the previous work. The energy levels were extended is up to 34-.更多还原
