Neutrons are an excellent probe of the physics of unpaired electrons. We introduce a formalism to compute the neutron magnetic form factor within a first-principles Density Functional Theory (DFT) + Dynamical Mean Field Theory (DMFT) calculations. We use our method to compute the form factor of the heavy fermion superconductor PuCoGa5. We find that the local physics of this material is described by a mixed valence mechanism of the type observed in elemental Plutonium. In my talk I will first briefly introduce the DFT +DMFT algorithm and show how we compute the magnetic form factor. Then I will talk about the physics of PuCoGa5".
