Interaction of particles in a Thin Slice matter

  1. May 31, 2007 #1
    I am trying to find more information on the above subject. Can anyone point me in the right direction?
    Also: What formula do you use to work out the volume of the material?
    Any help, greatly appreciated :smile:

    Can you be a little more specific? Set up the problem that you want help with in detail and maybe we can help.

    Sure... sorry that was a bit vague.
    I'm studying radiation physics, and finding the study material a bit vague.
    Given factors for the problem: 10 molecules exist in a thin sheet of material that is 0.1 micrometers thick, and has a facial area of 1micrometer by micrometer square. Calcualte the volume of the material, and number of molecules per cubic meter and cross section (area) of each molecule. I have 2 physics text books, and neither have much in them.
