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…
