Resonances in Positron--Mg Scattering
Resonances in Positron-Mg Scattering

We present the results for resonances in positron--Mg scattering at low impact energy (0--5.0eV) by using the momentum space coupled-channel optical (CCO) method in momentum space. The S-partial wave resonance at 3.880eV, P-partial wave resonance at 4.020eV, and D-partial wave resonance at 4.267eV are found.
