| 英文摘要 | Absolute double differential cross section spectra of o-2 at scattering angles of 0 degrees, 2 degrees, 4 degrees, 6 degrees, and 8 degrees below 119 ev have been determined by the angle-resolved electron-energy-loss spectrometer at an incident electron energy of 2500 ev. some features above the first ionization threshold stand out as the momentum transfer square k-2 increases. based on our experimental results and theoretical analysis, they are assigned to the optically forbidden rydberg series of 2 sigma(-1)(u)(c (4)sigma(-)(u))np sigma(u) (3)sigma(-)(g) (n=2-6) and the inner-valence transition of (2 sigma(g))(-1)(1 pi(g))(3) (3)pi(g)<- x (3)sigma(-)(g), respectively. furthermore, the observed energy positions of 2 sigma(-1)(u)(c (4)sigma(-)(u))np sigma(u) (3)sigma(-)(g) (n=2-6) confirm a theoretical prediction [zhong and li, j. phys. b 37, 735 (2004)] that the eigenquantum defects show an evident oscillation due to the presence of shape resonance. |
