{HeH $^+$}分子离子的光解离

Photodissociation of the {HeH$^+$} molecular ion

Irina Dumitriu, Alejandro Saenz

摘要:

在Born-Oppenheimer近似下计算了分子离子HeH $^+$的光解离截面,并考虑了不同的初始振动和转动状态.结果进行了比较,最近的数据从自由电子激光实验进行的FLASH设施[H. B。Pedersen {\it等人},物理修订版信函98,223202,(2007)]。在实验不确定度范围内,理论和实验结果是一致的。

英文摘要:

The photodissociation cross section of the molecular ion HeH$^+$ was calculated within the Born-Oppenheimer approximation for a parallel, a perpendicular, and an isotropic orientation of the molecular axis with respect to the field, considering also different initial vibrational and rotational states. The results were compared to recent data from a free-electron laser experiment performed at the FLASH facility [H.B. Pedersen {\it et al.}, Phys. Rev. Lett. 98, 223202, (2007)]. Within the experimental uncertainties theoretical and experimental results are compatible with each other.
