A new factorization method for studying fusion is presented. It provides a method for simulating three-dimensional collisions in locally isotropic plasmas using a density scaling argument based on a one-dimensional model . This model includes ion movement, Coulomb collisions and Gamow type tunneling probabilities in an un-magnetized deuterium-tritium plasma . The main advantage of this method is a reduction in complexity over three-dimensional approaches. Particle-in-Cell numerical simulations based on this model predict three-dimensional fusion reactivity  and collision rates for ions and electrons  that are in excellent agreement with theory, suggesting that the model may be useful in modeling burning plasmas.
