Experimental Study of Dissociative Attachment in Optically-Pumped Lithium Molecules.

Abstract

The first experimental observations of dissociative attachment in lithium dimmer molecules are presented, Lithium molecules are optically pumped via the Li2(B) electronic state into selected levels of the ground electronic state. Low energy electrons are created by two-step laser photoionization of lithium atoms. Product Li ions are detected by time-of-flight spectrometry. Preliminary analysis of the data gives a rate constant of .3 x 10 to the 8th power cc/sec for the attachment of 0.1 eV electrons to lithium vibrational states v = 8 to v =12. without strong dependence on the selected states. Originator-supplied keywords include: Dissociative Attachment.
