| 摘 要： | 本文研究了ＣＣｌ４低温（１３０Ｋ）吸附于石英表面上经紫外激光辐照后引起的脱附过程。由时间分辨四极质谱测得脱附产物的飞行时间谱表明，在高激光能量密度下，表面上吸附厚层的ＣＣｌ４分子发生爆炸脱附，超热的ＣＣｌ４分子最高动能可达３．５ｅＶ。

| Abstract: | The ultraviolet (355 nm) laser induced desorption of CCl4 cryogenic film on quartz surface at 130 K is investigated using time-resolved quadrupole mass spectroscopy. The measured time-of- flight spectra of desorbed species show that the explosive desorption takes place at high laser fluence and high multilayers of CCl4. The hyperthermal CCl4 molecule with kinetic energy of 3.5eV is obtained at laser fluence of 75 mJ/cm2. |
