To verify the estimated mass of a neutron

  1. Mar 13, 2005 #1
    with the use of the conservation of momentum..

    Is it possible? what does it exactttly mean anyways? :bugeye:

    I was suppose to research on..

    ... Geiger-Marsden experiment and Rutherford's model and answer a few questions.. one of them was to explain "how conservation of momentum could be used to verify the estimated mass of the neutron", but i just have no idea how or where to start from.. :confused:

    Thanks for replyin!

    Rutherford's experiment was done with alpha particles & gold nuclei.The neutron's mass in not a direct variable...

    Here,conservation of energy is much more usefuln,but that depends on what you wanna get...

    So neutrons have actually nothing to do with

    ..the conservation of momentum?

    Not with Rutherford,Marsden,Geiger,1909,alpha particles & Gold nuclei...

    With other experiments...

    I see..

    could u just give an example of any theory it would work for?


    thanks a lot for helping!!

    There is a large disparity in mass between the Au nucleus on the one hand and the alpha particle and neutron on the other. A case of a marble wacking into a stationary bowling (sticking?) and knocking out a pea sized peice of the bowling ball. So couldn't it be approximated by the momentum of the alpha = momentum of neutron?
