| 摘 要： | This paper applies the multiple ellipsoid model to the 16 Ne (20 Ne,28 Ne,34 Ne)-Na 2 collision systems,and calculates integral cross sections for rotational excitation at the incident energy of 190 meV.It can be seen that the accuracy of the integral cross sections can be improved by increasing the number of equipotential ellipsoid surfaces.Moreover,by analysing the differences of these integral cross sections,it obtains the change rules of the integral cross sections with the increase of rotational angular quantum number J,and with the change of the mass of isotope substitution neon atom.Finally,the contribution of different regions of the potential to inelastic cross sections for 20 Ne-Na 2 collision system is investigated at relative incident energy of 190 meV.

| Abstract: | This paper applies the multiple ellipsoid model to the 16Ne (20Ne, 28Ne, 34Ne)--Na2 collision systems, and calculates integral cross sections for rotational excitation at the incident energy of 190 meV. It can be seen that the accuracy of the integral cross sections can be improved by increasing the number of equipotential ellipsoid surfaces. Moreover, by analysing the differences of these integral cross sections, it obtains the change rules of the integral cross sections with the increase of rotational angular quantum number J', and with the change of the mass of isotope substitution neon atom. Finally, the contribution of different regions of the potential to inelastic cross sections for 20Ne--Na2 collision system is investigated at relative incident energy of 190 meV. |
