Homework Help: Energy of alpha particle and quantum tunneling

  1. May 2, 2009 #1
    1. The problem statement, all variables and given/known data
    Alpha decay typically involves an alpha-particle of 5-6Mev. How can this be explained using quantum mechanics?

    2. Relevant equations

    3. The attempt at a solution
    I think I need to work out the potential barrier and then work out how much KE an alpha particle has once it has tunnelled out, by convertig KE to PE.
