Transient Molecular-Ion Formation in Rydberg-Electron Capture

摘要: Resonance structure has been observed in total cross sections for the capture of an electron from a Rydberg-state atom by singly charged projectile with speed {ital v}{sub ion} comparable to Bohr velocity e}} target electron. Prominent peaks data at reduced velocities {tilde v}}={ital ion}/{ital e}}=0.8 and 0.5 result two distinct mechanisms which passes once or three times, respectively, through midplane between nuclei. The three-swap peak v}}=0.5 marks high-velocity limit molecular-ion formation is shared charge centers. This illustrates that new paradigms collision dynamics may emerge when reactions are examined near correspondence principle limit.
