理论研究强激光场中2 pz态氢原子的电离
Theoreticalstudies on the ionization rate of 2 pz hydrogen atom in an intense laser field
摘要
Abstract
The ionization rate of excited state hydrogen atom has been investigated using the velocity gauge and a simple ionization rate formula for the 2pz state of a hydrogen atom has been derived in the linearly polarized laser field when both conditions:ω<< 1 a.u.andγ<< 1 (ωis the laser frequency andγis the Keldysh parameter)are satisfied.The formula shows that in the low-frequency limit the ion-ization rate is proportional to the laser frequencyω.The concise formula of ionization rate may provide more insight into the ionization mechanism for the excited state of a hydrogen atom.关键词
