Glauber近似下n=3和n=4能级的电子-氢激发

Electron-hydrogen excitation to the n=3 and n=4 levels in the Glauber approximation

Victor Franco

摘要:

本文用Glauber近似计算了电子碰撞激发氢原子到n=3和n=4能级的微分和积分截面。结果进行比较,在20,30,40,和60 eV的测量,也显示为120和480 eV。在所考虑的所有能量下,在动量转移不太大的情况下,计算的n=3微分截面与计算的n=4截面在性质上类似,但比计算的n=4截面大3倍。计算的积分截面在41 eV附近达到宽的最大值。

英文摘要:

We have calculated the differential and integrated cross sections for excitation of atomic hydrogen to its n=3 and n=4 levels by electron impact using the Glauber approximation. Results are compared with measurements at 20, 30, 40, and 60 eV and also shown for 120 and 480 eV. At momentum transfers not too large at all energies considered, the calculated n=3 differential cross sections are qualitatively similar to but a factor of somewhat less than 3 larger than the calculated n=4 cross sections. The calculated integrated cross sections attain broad maxima near 41 eV.
