Homework Help: Kinetic energy of alpha particle during decay

  1. May 9, 2010 #1
    1. The problem statement, all variables and given/known data

    Show that kinetic energy acquired by an alpha particle during an alpha decay is

    Talpha=Q/[1+[maplha/mD]


    2. Relevant equations

    Q=[mP-mD-malpha]c^2


    3. The attempt at a solution

    Q is the release of energy which is acquired by the daughter nucleus and the alpha particle in the form of KE. I'm just not sure how to determine the KE will be split between the two

    Apply conservation of energy in conjunction with conservation of momentum. This will lead to a unique solution for the kinetic energy possessed by each particle.
