摘要:

我们研究了$_Λ^{9}$ Be核的束缚态和共振态的性质。为了揭示这些状态的性质,我们使用三簇$2α+Λ$微观模型。该模型采用高斯基函数和振子基函数,将三团簇薛定谔方程简化为两体类多通道问题,其中两团簇子系统($_Λ^{5}$ He和$^8$ Be)处于束缚态或伪束缚态.分析了团簇极化对$_Λ^{9}$ Be中共振态能量和宽度的影响以及对$_Λ^{5}$ He+ $α$弹性和非弹性散射的影响。

英文摘要:

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.
