Observation of Superdeformation in 79Kr

摘要: 通过55Mn(30Si,αpn)反应布居了79Kr的高自旋态.用GASP阵列配以由40个ΔE×ESi(Au)望远镜所组成的带电粒子球实现γγγ-带电粒子符合测量.观测到由相对强度为(2.7±0.3)%的8条级联γ跃迁所组成的79Kr高自旋超形变转动带.除了在转动频率ω>0.95MeV处急剧下降外,该带的动力学转动惯量近乎常数(22ñ2/MeV)并被解释为具有四极形变参数β2=0.51以及本征侵入组态为π50ν51. High-spinstates in 79Kr were populated via the fusion evaporation reaction 55Mn (30Si,αpn)at 130 MeV.Promptγ γγcharged particle coincidences were measured by using the GASP array in conjunction with the ΔE×E Si(Au) charged particle ball.Asuperdeformed band consisting of 8 γray transitions with an intensity of (2.7±0.3)% has been indentified in 79Kr.The dynamic moment of inertia for the band is nearly constant at approxately 22ñ2/MeV below arotational frequency of 0.95 MeV...
