- Homework Statement
- Hello,

Imagine the Hamiltonian of a two-atom molecule, you have the kinetic energy of one+the other and then you have a relative distance potential ( V(|r2-r1|^2), ri is 3 dimensional).

How to change the variable to solve the following integral with infinite limits?

- Relevant Equations
- Intg( exp( |r2-r1|^2) dr1dr2)

I think its going to be intg(dr2)intg(exp(r^2) dr) or something like that.
