论文摘要
使用$^{8} $的弹性α-α散射和共振结构，应用了两个群集的微观模型。该模型是谐振组方法的代数版本，该方法使用完整的振荡器函数集来扩展两集群系统的波浪函数。集群之间的相互作用是由谷仓纳加塔，明尼苏达州和沃尔科夫的众所周知的半现实核定核子电位确定的。共振波函数的详细分析在振荡器，坐标和动量空间中进行。保利原理对$^{8} $的波函数的影响是连续频谱状态的。
A two-cluster microscopic model is applied to study elastic alpha-alpha scattering and resonance structure of $^{8}$Be. The model is an algebraic version of the Resonating Group Method, which makes use complete set of oscillator functions to expand wave function of two-cluster system. Interaction between clusters is determined by well-known semi-realistic nucleon-nucleon potentials of Hasegawa-Nagata, Minnesota and Volkov. Detail analysis of resonance wave functions is carried out in oscillator, coordinate and momentum spaces. Effects of the Pauli principle on wave functions of the $^{8}$Be continuous spectrum states are thoroughly studied.
