论文摘要
我们研究了9个是基于非本地$α-$ n和$α-α$电势的基础能量，这些电势来自群集有效场理论。相互作用的短途依赖性通过动量截止。拟合潜在参数以重现散射长度和有效范围。我们在动量空间中的非对称超透明谐波（NSHH）代码中实施了此类潜在模型。另外，我们计算各种α核的基态能量。通过使用Lorentz积分转换（LIT）方法计算9BE的光分离的计算正在进行中。
We study the 9 Be ground-state energy with non-local $α-$n and $α-α$ potentials derived from Cluster Effective Field Theory. The short-distance dependence of the interaction is regulated with a momentum cutoff. The potential parameters are fitted to reproduce the scattering length and effective range. We implement such potential models in a Non-Symmetrized Hyperspherical Harmonics (NSHH) code in momentum space. In addition we calculate ground state energies of various alpha nuclei. Work is in progress on a calculation of the photodisintegration of 9Be with the Lorentz Integral Transform (LIT) method.
