Bremstrahlung cross-section for nucleus and electrons

  1. Feb 21, 2012 #1
    1. The problem statement, all variables and given/known data

    Explain what is meant by Bremsstrahlung. Which cross-section is higher for atoms with Z>1: Bremsstrahlung on the atomic nucleus or on the atomic electrons? Why?

    3. The attempt at a solution

    I explained what Bremsstrahlung was just by copying from the notes. I am not sure about which cross-section is higher. So far I wrote:

    Bremsstrahlung on the atomic nucleus because the nucleus is bigger than the electrons so they have a larger cross-section.

    Is this correct? If so, is there some way to expand upon that reason / are there any other reasons? My notes and textbooks almost say nothing about Bremsstrahlung cross-sections.

    Thanks if you help.
