【 摘 要 】

Utilizing the high-resolution inelastic x-ray scattering technique, absolute inelastic squared form factors of four vibronic series belonging to the B1Σu+, C1Πu, EF1Σg+and B'1Σu+electronic states of molecular hydrogen are determined experimentally. In addition, the same inelastic squared form factors are calculated by the multi-reference single and doubleexcitation configuration-interaction method for the B1Σu+, C1Πu, EF1Σg+. Apparent differences are observed between the present experimental results and all available calculated ones.
