In closed quantum systems, such processes are attributed to the transfer of energy from collective motion to single-particle degrees of freedom; however, the quantum many-body dynamics of this evolutionary process is poorly understood. To explore energy dissipative phenomena and equilibration dynamics in one such system, an experimental investigation of deep-inelastic and fusion-fission outcomes in the ^{58}Ni+^{60}Ni reaction has been carried out. Experimental outcomes have been compared to theoretical predictions using time dependent Hartree-Fock and time dependent random phase approximation approaches, which, respectively, incorporate one-body energy dissipation and fluctuations. Excellent quantitative agreement has been found between experiment and calculations, indicating that microscopic models incorporating one-body dissipation and fluctuations provide a potential tool for exploring dissipation in low-energy heavy ion collisions.The authors also acknowledge support from the Australian Research Council through Grants No. DE140100784, No. FT120100760, No. FL110100098, No. DP130101569, No. DP140101337, and No. DP160101254; from the NCRIS program for accelerator operations; and from the Polish National Science Centre (NCN) Grant, Decision No. DEC-2013/ 08/A/ST3/00708.
