摘要：

We have used a molecular-beam photoionization technique to probe the vibrational-energy distribution of SF6 molecules excited by an intense CO2 laser at energy fluences close to and below the dissociation threshold. We observe a significant bottleneck at low laser intensities. Even at laser fluences close to the dissociation threshold, most of the molecules remain in the discrete levels, and only a small fraction (˜10-25%) are excited into the quasi-continuum. © 1979, Optical Society of America.
