The production and destruction of metastable negative ions: Progress report, September 1, 1986-August 31, 1987
Technical Report
·
OSTI ID:6494657
This report describes the progress made during the present grant period in the investigation of the properties of metastable negative ions using fast-beam autodetachment and photodetachment spectroscopy. The autodetachment measurements involved an unsuccessful search for the metastable Ar/sup -/ ion and the determination of the ground state He-He potential curve over a limited range of internuclear distances using autodetachment spectroscopy of He/sub 2//sup -/. Preparations were made for photodetachment measurements on He/sup -/ and Ca/sup -/. An apparatus designed for photoelectron spectroscopy and cross section measurements was fabricated. A pulsed dye laser and optics for beam steering and polarization measurements were purchased.
