摘要：

We have examined the laser ionization of He-3 using 1.053-mum 1.5-ps laser pulses. The use of He-3 rather than He-4 in the experiment enables the detection of the second charge state separately from a troublesome background contaminant H-2+. In these experiments, the production of doubly charged ions is dominated by the sequential process rather than by the direct or simultaneous process.
