| 摘 要： | 理论研究了H_2~+在不同振动态下辐射高次谐波的特点.结果表明,在低振动态下,谐波辐射呈现红移现象.随着振动态增大,谐波红移现象逐渐减弱甚至消失.通过分析谐波辐射时频分析图以及双H核辐射谐波的特点,给出了振动态对H_2~+谐波辐射频移的原因.

| Abstract: | High-order harmonic generation from H2+ with different vibrational states has been theoretically investigated. The results show that the red-shifts of the harmonics can be found in the lower vibrational states. As the vibrational state increases, the red-shifts of the harmonics are decreased even disappeared. Through studying the time-frequency analyses of the harmonics and the contributions of the harmonics from the two-H nuclei, the reason behind the frequency modulation of harmonics can be given. |
