论文摘要
我们研究了$_λ^{9} $ be nucleus中绑定和共振状态的属性。为了揭示这些状态的性质，我们使用了三群$2α+λ$微观模型。该模型结合了高斯和振荡器的基础函数，并将三个群集的schrödinger方程降低到像多渠道问题一样的两体问题，其中两集群子系统（$_λ^{5} $ He和$^8 $ be）处于绑定或伪造的状态。簇极化对$_λ^{9} $的共振状态的能量和宽度的影响以及对弹性和无弹性$_λ^{5} $ he+$ a+$α$散射的影响。
We investigate properties of bound and resonance states in the $_Λ^{9}$Be nucleus. To reveal the nature of these states, we use a three-cluster $2α+Λ$ microscopic model. The model incorporates Gaussian and oscillator basis functions and reduces a three-cluster Schrödinger equation to a two-body like many-channel problem with the two-cluster subsystems ($_Λ^{5}$He and $^8$Be) being in a bound or a pseudo-bound state. Influence of the cluster polarization on the energy and widths of resonance states in $_Λ^{9}$Be and on elastic and inelastic $_Λ^{5}$He+$α$ scattering is analyzed.
