Ramsauer–Townsend effect

  1. Jan 16, 2014 #1
    I am currently about to do this experiment in my lab class. I had a couple of questions as I was reading over papers on the experiment:

    1) Why is it classically that the scattering of the electrons decrease monotonically when velocity increases? All of the papers and websites mentioned it, but didn't explain it.

    2) Why is there only one minimum? More specifically, is this fundamental to the Xenon gas (or noble gases)? If we used say, an Iodine gas, would we still get one minimum or even a minimum at all?

    I haven't started the experiment yet but I would like to have a deeper understanding of the concepts before I begin. Thanks for all the help in advance!
