| Título: | Vibrational excitation cross-section by positron impact: a wave-packet dynamics study |
| Autor(es): | Luis Argel Poveda Calviño Márcio Teixeira do Nascimento Varella José Rachid Mohallem |
| Resumen: | The vibrational excitation cross-section of a diatomic molecule by positron impact is obtained using wave-packet propagation techniques. The dynamics study was carried on a two- dimensional potential energy surface, which couples a hydrogenlike harmonic oscillator to a positron via a spherically symmetric correlation polarization potential. The cross-section for the excitation of the first vibrational mode is in good agreement with previous reports. Our model suggests that a positron couples to the target vibration by responding instantly to an interaction potential, which depends on the target vibrational coordinate. |
