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…
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…
Positronium formation and threshold behavior in positron-sodium collisions at low energies
Ning-Ning Gao, Hui-Li Han, Ting-Yun Shi
We investigate the elastic and inelastic scattering of positrons by sodium atoms in both the ground state, Na(), and excited states, Na*(, , ), using the hyperspher…
Investigation of Efimov Features and Universality in Rb-K Mixtures with finite-range interaction
Ning-Ning Gao, Hui-Li Han, Ting-Yun Shi
The study of Efimov features and their relationships in K-Rb Mixtures has generated extensive discussion, yet the discrepancy between Efimov universality predictions…
