标题： Beryllium-9 in Cluster Effective Field Theory

摘要： 我们研究了基于聚簇有效场理论导出的非局部${\alpha}-$n 和${\alpha}-{\alpha}$势的 9 Be 基态能量。通过动量截断来调节相互作用的短距离依赖性。势参数被拟合以再现散射长度和有效半径。我们在动量空间中的非对称化超球谐(NSHH)代码中实现了这些势模型。此外，我们还计算了各种 $\alpha$ 核的基态能量。目前正在进行 9 Be 光分解的洛伦兹积分变换(LIT)方法的计算工作。 显示英文摘要

摘要： We study the 9 Be ground-state energy with non-local ${\alpha}-$n and ${\alpha}-{\alpha}$ 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.
