Low-energy positron scattering from metastable helium
Ning-Ning Gao, Hui-Li Han, Ting-Yun Shi +1
Low-energy positron scattering from singlet and triplet metastable He() is investigated using the -matrix propagation method in hyperspherical coordinates. Elastic and pos…
Simultaneous Determination of Multiple Nuclear Parameters of Th Using Highly Charged Ions
Hong-Yuan Zheng, Yan-Ling Xu, Xi-Chen Yu +4
Development of a Th nuclear optical clock requires precise and model-insensitive nuclear-structure parameters, which presently suffer from limited accuracy and poor consist…
Ionization energies for Rydberg () states using the correlated B-spline basis function method
Jing Chi, Hao Fang, Yong-Hui Zhang +2
We extend the correlated B-spline basis function (C-BSBF) method to high-precision calculations of the ionization energies of helium Rydberg states (--). Using…
Characterizing resonances in positron-sodium scattering
Ning-Ning Gao, Hui-Li Han, Ting-Yun Shi +1
We investigate resonances in positron-sodium scattering using the -matrix propagation method formulated in hyperspherical coordinates. The interaction between the sodium core an…
