Direct measurement of dissipation in the ³⁵Cl + ¹²C reaction at 43 MeV/nucleon

Characteristics of ³⁵Cl+¹²C collisions at 43 MeV/nucleon have been studied for events with total charge detected (ΣZ = 23). It is shown that, while single-source events are present in the data, the binary nature of the collision is dominant. For binary events, the emitting sources (projectilelike and targetlike) were reconstructed independently allowing a direct measurement of the total dissipated energy. It is found that up to 75% of the available energy is dissipated and the significant momentum transfer of the selected events leads to the “equal temperature limit.”
