Already it is on title !

attachents provide the most relevant equations i could find.

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 don't know if and how could this be related to the ground state eigenfunction.
i can't 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)}
