Show affiliationsThe photoionization of seeded carbon bisulfide molecular beam by a 1064nm nanosecond Nd-YAG laser with intensities varying from 0.8 × 1011 to 5.6 × 1011 W/cm2 have been studied by time-of-flight mass spectrometry. Multiply charged ions of Sq+ (q = 2-6) and Cq+ (q = 2-4) with kinetic energy of hundreds of electron volts have been observed, and there are strong experimental evidences indicating that those multicharged ions originate from the ionization of CS2 neat clusters in the beam. An electron recolliding ionization model is proposed to explain the appearance of those multiply charged atomic ions under such low laser intensities.
