Nuclear force saturation

  1. Apr 26, 2005 #1
    I have solutions to a past paper essay question that indicates that the student should explain the saturation of the nuclear force in terms of the stability of the helium nucleus. I do not see how to do this, I can only explain the saturation of the force in that the nuclear biniding energy is proprtional to A, not A squared.
    So, how does the stability of the helium nucleus indicate the nuclear force is saturated?

    This might be of some help


    At a fairly simple level, I think the stability of the helium nucleus is an indication of saturation because there are no stable nuclei with 5 nucleons, indicating that there is not enough force to bind and additional nucleon to a helium nucleus. Hence, saturation
