Generalized oscillator strengths of the a″1Σ+g(v′ = 0) and a″1Σ+g(v′ = 1) +b1Πu(v′ = 0) of nitrogen studied by high-energy electron scattering
摘要
Abstract
The generalized oscillator strengths of a″1Σ+g(v′ =0)and a″1Σ+g(v′ =1) +b1Πu(v′ =0)of molecu-lar nitrogen were measured at a high incident electron energy of 1500 eV and a high energy resolution of 70 meV with the aid of the relative flow technique. The present results are apparently different from the X-ray scattering ones in the large momentum transfer region,which indicates that for a″1Σ+g(v′ =0)the first-order Born approx-imation is not satisfied at the incident electron energy E0= 1500 eV in the large momentum transfer region. The agreement of the present results with the X-ray scattering ones for a″1Σ+g(v′ = 1) +b1Πu(v′ = 0)in K2< 2 a.u. indicates that the first-order Born approximation is satisfied at the incident electron energy E0= 1500 eV for b1Πu(v′ = 0).关键词
