摘要
REMPI technique has been widely used to study the vibrational branching ratios of photoionization of excited states of molecules for the recent decades. It has been found out that the vibrational branching ratios of H<sub>2</sub> C<sup>l</sup>π<sub>u</sub> photoionization are strong non-Franck-Condon. The present letter, starting from the anharmonicity of H<sub>2</sub> and H<sub>2</sub><sup>+</sup>,
