We compute the moments and free cumulants of the measure $ρ_t: = π_t ⊠ π_t$, where $π_t$ denotes the free Poisson law with parameter t > 0. We also compute free cumulants of the symmetrization of $ρ_t$. Finally, we introduce the free symmetrization of a probability measure on ℝ and provide some examples.
