The energy spectra of electrons detached from O-and S ions by 488.0nm and 514.5 nm photons have been measured with high electron energy resolution (5 meV) in order to determine the branching ratios for the various 2P3/2.1/2 --" aP2, 1.o fine-structure transitions together with their respective angular distributions. Detailed information on the relative importance of the s-and d-wave continuum is obtained.

“…The photodetachment cross section of O -calculated by Chase and Kelly (1972) at photon energies between EA and 1107.665 'B is in agreement with that measured by Branscomb et al (1965), and this theoretical photodetachment cross section of O -is used at photon energies more than 3.8 eV. The resulting calculated value of K 1 det (O -) is equal to 2.1 s -1 .…”

“…The cross section for photodetachment of atomic negative oxygen ions has been measured by Branscomb et al (1965), Lee and Smith (1979), and Hlavenka et al (2009) in the photon energy range from EA to about 3.8 eV. The photodetachment cross section of O -calculated by Chase and Kelly (1972) at photon energies between EA and 1107.665 'B is in agreement with that measured by Branscomb et al (1965), and this theoretical photodetachment cross section of O -is used at photon energies more than 3.8 eV.…”

“…For purposes of illustrating the effect of the method, it is tacitly assumed that the diameters of the photon and negative ion beams perfectly overlap with respective average values for photons and adjustable values for the negative ion beams The cross-section for photo-detachment of O À ( 2 P 1/2 ) has been theoretically studied (e.g. the work described in [20]) and experimentally measured by several groups, including the work described in [21][22][23]. According to the measurements of [21], the cross-section for photo-detachment of O À with 2.336 eV photons is 6.4 Â 10 À18 cm 2 .…”

According to the measurements of [21], the cross-section for photo-detachment of O À with 2.336 eV photons is 6.4 Â 10 À18 cm 2 . This value is in reasonable agreement with the theoretical value calculated by Robinson and Geltman [20] of 7.45 Â 10 À18 cm 2 .…”
