| Abstract: | The photoionization of seeded carbon bisulfide molecular beam by a
1064\,nm nanosecond Nd-YAG laser with intensities varying from
$0.8\times10^{11}$ to $5.6\times10^{11}$\,W/cm$^{2}$ have been
studied by time-of-flight mass spectrometry. Multiply charged ions
of S$^{q + }$ ($q$ = 2--6) and C$^{q +}$ ($q$ = 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 CS$_{2}$ 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. |
