Natural and unnatural parity resonance states in positron-hydrogen scattering

We present an investigation of resonances with natural and unnatural parities in positron scattering with atomic hydrogen. The complex scaling method has been used. Resonance states for natural parity with total angular momenta and unnatural parity with are calculated. Resonance energies and widths...

Beschreibung
Zusammenfassung:	We present an investigation of resonances with natural and unnatural parities in positron scattering with atomic hydrogen. The complex scaling method has been used. Resonance states for natural parity with total angular momenta and unnatural parity with are calculated. Resonance energies and widths are reported and compared with other theoretical calculations.
