 Homework Statement:

Hello,
Imagine the Hamiltonian of a twoatom molecule, you have the kinetic energy of one+the other and then you have a relative distance potential ( V(r2r1^2), ri is 3 dimensional).
How to change the variable to solve the following integral with infinite limits?
 Relevant Equations:
 Intg( exp( r2r1^2) dr1dr2)
I think its going to be intg(dr2)intg(exp(r^2) dr) or something like that.
