Abstract We have developed a very schematic static model to calculate the most probable amount of linear momentum transfer, $$\tilde \rho$$ , that a projectile can transmit to a fusing system in heavy ion collisions at bombarding energies between ∼10 and 20 MeV/u. This approach estimates the conditions necessary in phase space for nucleons to be emitted by the mean field of one of the two nuclei. Due to its simplicity this model gives a qualitative description of the data and it is only expected to provide some general numerical trends of $$\tilde \rho$$ as a function of the macroscopic parameters of the reaction. It is found that $$\tilde \rho$$ depends not only on the bombarding energy per nucleon but also on the masses of the projectiles and targets. Finally, the question of the amount of maximum energy that a nucleus can sustain under the condition of global statistical equilibrium is investigated. It is found that the mass asymmetry of the system is an all important parameter in determining the limits of fusion related to this maximum excitation energy content.
