寻找原子核拉长态的主要兴趣在于它是一个纯核壳模型组态,它常常被用来定义相应的组态空间大小,确认多核子壳模型计算中的剩余相互作用,并且在全微观三核子转移反应DWBA分析中提供好的波函数。实验上观测到的纯壳模波函数并不多,主要是在一些较轻的核上观测到的,此工作的主要目的是在中等重核上观测寻找原子核拉长态。利用ΔE-E望远镜及北京Q3D磁谱仪系统,在HI-13串列加速器提供的35MeVα离子轰击下,测量了~(56)Fe(α,d)~(58)Co核反应的精细能谱和微分截面角分布。借助全微观DWBA理论分析,相 The main interest in finding an elongated state of the nucleus is that it is a pure-core shell model configuration which is often used to define the size of the configuration space and to confirm the remaining interactions in the calculation of the multi-core shell model, Transfer reaction DWBA analysis provides a good wave function. Experimental observations of pure shell mode wave function is not much, mainly observed in some lighter nuclei, the main purpose of this work is to observe in the medium heavy nuclear looking for nuclear elongated state. Using the ΔE-E telescope and the Beijing Q3D magnetic spectrometer system, the fine energy spectra of ~ (56) Fe (α, d) ~ (58) Co nuclear reaction were measured by 35 MeVα ion bombardment provided by HI-13 tandem accelerator and Differential cross section angle distribution. With the help of the whole micro DWBA theory analysis, phase
