P. Erman et al., VISIBLE AND VUV FLUORESCENCE FROM SYNCHROTRON-RADIATION-INDUCED PHOTOIONIZATION AND PHOTODISSOCIATION OF MOLECULAR-OXYGEN, Physica scripta. T, 49(3), 1994, pp. 308-315
Photon induced fluorescence from O2 has been studied in various emissi
on regions 1150-6500 angstrom in the excitation range 14-28 eV using t
he Swedish synchrotron facility MAX in Lund. A rich line structure is
observed which is interpreted in terms of autoionization and dissociat
ion of Rydberg levels converging to the a, b, c, and B states in O2+.
New features have been observed, for instance, concerning the (c 4SIGM
A(u)-) 3ssigma(g) Fano resonance which has been viewed in detail in di
fferent detection channels including O2+ and O+ ions.
