| 摘 要： | 用重离子熔合蒸发反应布居A～110核区缺中子奇奇核106,108Ag的高自旋态，分别在这两个核中找到了类似104Rh中基于πg9/2 νh11/2组态的手征双带结构。它们的能级能量、旋称及B(M1)/B(E2)随角动量的变化关系符合手征带的特征。然而，进一步分析发现，106Ag、108Ag双带之间的转动惯量及准粒子角动量顺排存在较大差别，说明两者的晕带和伴带所基于的核芯形变与角动量耦合模式并不一致。

| Abstract: | High spin states of 106,108Ag were studied by using fusion evaporation reaction on Beijing HI-13 Tandem Accelerator.The negative-parity bands were updated for both nuclei.Doublet bands similar to chiral bands in 104Rh were indentified in 106,108Ag respectively.But there is much difference of the moment of inertia and alignment between the yrast and yrare bands in both of them.It may result from the different deformations of the core and angular momentum coupling mode between valence particles and the inner-... |
