Sequential over-barrier ionization of multi-electron atoms in the tens-to-hundreds keV/u energy range 下载免费PDF全文
Our previous work on the classical over-barrier ionization model for helium double ionization is extended to the complex multi-electron system of Ne.The total and q-fold ionization cross sections are calculated at energies ranging from a few tens to several hundred keV/u.The calculation results are in good agreement with the experimental data,and the energy dependence of the cross sections suggests that the multi-ionization of a strong perturbated complex atom is probably the sequential over-barrier ionization process. 相似文献

红外光谱可以清晰地展示出萃取剂与被萃取物质之间的相互作用关系,实验采用三辛胺(TOA)作为萃取剂基于膜分散萃取技术研究了三辛胺与丙酸的结合方式。通过对纯丙酸,丙酸正辛醇溶液,以及萃取前后的有机相进行红外光谱表征,结果证明TOA与丙酸存在着氢键结合与离子缔合的两种结合方式,而且通过峰面积的对比,离子缔合的萃合物的量要远大于氢键缔合的萃合物。 相似文献
