Outline of Final Research Achievements

Experiments were conducted with the aim to produce a beam of metastable lithium ions by photoionizaingionize gasphase lithium atoms with synchrotron radiation. The metastable lithium ion beam was then crossed with a target atom beam to observe Penning ionization. Individual Penning electrons were observed, utilizing a modified photoion time of flight spectrometer. Subsequently, an attempt was made at the advanced light source to energy analyze the Penning electrons , but the results fell short of conclusive determination. On the other hand, very interesting results were obtained on the post collision interaction and photoelectron recapture phenomena.
