摘要:

用波长为400 nm、脉冲宽度为150 fs的激光,在强度高达6 × 10 ^{13} Wcm^{-2}的条件下,研究了镁的多光子电离和光电子能谱。结果表明,各种不同的电离机制发挥了作用,在这两种类型的光谱。一个理论模型描述的过程,并确定电离的路线。这项工作证明了原子的双电子性质在解释实验结果方面的重要性。

英文摘要:

The multiphoton ionization and photoelectron spectra of magnesium were studied at laser intensities of up to 6x10^{13} Wcm^{-2} using 150 fs laser pulses of a wavelength of 400 nm. The results indicated that a variety of different ionization mechanisms played a role in both types of spectra. A theoretical model describing the processes is presented and the routes to ionization are identified. The work demonstrates the significance of the two-electron nature of the atom in interpreting the experimental results.
