Homework Help: Write down the ground state eigenfunction (and spin) of Helium.

  1. Dec 9, 2011 #1
    1. The problem statement, all variables and given/known data
    Already it is on title !!!

    2. Relevant equations
    attachents provide the most relevant equations i could find.

    3. The attempt at a solution
    I have found some old books written in 1920 decade ,dealing with this subject,but the solution they provide seems very hard understand,although it might be correct.

    http://books.google.co.uk/books?id=...e&q=helium ground state eigenfunction&f=false

    i have in my possesion proof of the formula for the expectation energy of helium atom.
    But i dont know if and how could this be related to the ground state eigenfunction.
    i cant really provide more relevant formulas ,but it must be appreciated that this is not an easy problem.

    In the meantime i have found very important additional information using the textbook of chris foot called atomic physics.
    The total groundstate eigenfunction ψ of helium must be the product of spin part and spatial part i.e

    ψ= ψspin ψspatial= (according to this textbook) =( ms) (u1sunl) = (according to tables provided in this book i.e table 2.2 )= {√1/4π}{(z/a)3/2 (2e-p)}
