Abstract

The cross sections for one-, two-, and three-photon detachment from fluorine negative ions have been measured using light at the fundamental and harmonic frequencies of a 1064-nm pulsed neodymium-doped yttrium aluminum garnet laser. The ions were stored in a Penning ion trap, the depletion due to illumination was measured, and the data were fitted to a model for stored ions illuminated by pulsed light. The values obtained for the detachment cross sections are (1)=2.8(5)×10-18 cm2, (2)=2.0(7)×10-50 cm4 sec, and (3) =7.9-3.6+6.6×10-83 cm6 sec2. These values are compared with theoretical calculations and other experimental results.
