How the Pauli exclusion principle affects fusion of atomic nuclei

Simenel, Cedric; Umar, A S; Godbey, K; Dasgupta, Mahananda; Hinde, David


The Pauli exclusion principle induces a repulsion between composite systems of identical fermions such as colliding atomic nuclei. Our goal is to study how heavy-ion fusion is impacted by this "Pauli repulsion." We propose a new microscopic approach, the density-constrained frozen Hartree-Fock method, to compute the bare potential including the Pauli exclusion principle exactly. Pauli repulsion is shown to be important inside the barrier radius and increases with the charge product of the...[Show more]
