分子轨道与强场近似

Molecular orbitals and strong-field approximation

Thomas Kim Kjeldsen, Lars Bojer Madsen

摘要:

V.I. Usachenko和S.- I. Chu [Phys. Rev. A { \bf 71},063410(2005)]讨论了速度规范公式中的分子强场近似,并指出我们早期的一些速度规范计算是不准确的。在这里,我们评论的结果Usachenko和朱。首先,我们证明了Usachenko和Chu使用的分子轨道不具有正确的对称性,其次,用两个原子轨道的单一线性组合来描述分子轨道是一种过度简化。最后,给出了广义Bessel函数的一些数值,以供比较.

英文摘要:

V.I. Usachenko and S.-I. Chu [Phys. Rev. A {\bf 71}, 063410 (2005)] discuss the molecular strong-field approximation in the velocity gauge formulation and indicate that some of our earlier velocity gauge calculations are inaccurate. Here we comment on the results of Usachenko and Chu. First, we show that the molecular orbitals used by Usachenko and Chu do not have the correct symmetry, and second, that it is an oversimplification to describe the molecular orbitals in terms of just a single linear combination of two atomic orbitals. Finally, some values for the generalized Bessel function are given for comparison.
