Photoionization Studies Of Atomic Oxygen And Nitrogen

Photoionization cross sections for atomic oxygen and nitrogen have been measured from their respective thresholds to 100Å (for 0) and to 500R (for N). Previously unobserved structure in atomic oxygen is reported between 440 and 481R. Data which extends the atomic nitrogen cross sections to 100Å and data on the cross section for 02+ production are currently being analyzed.
