An atomic oxygen target for absolute differential cross section measurements

[摘要] An atomic oxygen target suitable for absolute differential cross sections has been developed. Molecular oxygen gas is partially dissociated in a microwave discharge and flowed through a collision cell to serve as a fast beam target. Determination of the atomic oxygen density is carried out using an electron impact time-of-flight mass spectrometer, which uses the exit aperture of the cell as a sample leak.
