OSTI ID:6057847
Experimental work has been directed primarily determining properties of metastable autodetaching negative ions, with a smaller effort directed to their production in beams, as well as the production and photodetachment of Li/sup -/ beams. Properties of particular concern were the photodetachment cross sections, energy levels, and autodetachment lifetimes. Detailed studies have been made of resonant structures in the photodetachment of He/sup -/ and Li/sup -/ negative ions. Some previously reported metastable ions were found to be probably nonexistent, while others were given the first experimental proof, and one unpredicted species He/sub 2//sup -/ was discovered. A long-lived auto-detaching form of OH/sup -/ was also observed. Total neutralization cross sections were measured as functions of beam energy for Li(+) in Mg, Ca, Sr, and Ba, and cross sections were calculated for Li(+) + Ca. (Author)
