I want to calculate $\int \phi_{A}(r)\phi_{B}(r)\phi_{C}(r)\phi_{D}(r)d^{3}r$ where $\phi_{A}(r)=(x-A_{x})^{l1}(y-A_{y})^{l2}(z-A_{z})^{l3}e^{-\alpha |r-A|^{2}}$. l1, l2 and l3 are integers Can you suggest any book and any code in c++/matlab that can calculate this quantity?

Welcome to SE. Please note that these are not Gaussians. Also, I don't see the direct connection to physics. – Semoi Apr 09 '21 at 17:05

If you want or need to do it numerically, why can’t you use this? – G. Smith Apr 09 '21 at 17:27

It should be doable analytically in spherical coordinates, but expanding it will produce a large number of terms. – G. Smith Apr 09 '21 at 19:52
