Neutron multiplicities, folding angle distribution, mass and mass-energy distribution are measured for the compound nucleus $^{210}\mathrm{Po}$ populated through $^{12}\mathrm{C}+^{198}\mathrm{Pt}$ reaction at an excitation energy of 61.6 MeV. The neutron multiplicities compared with statistical model code joanne2 to extract total fission time nucleus. $({\ensuremath{\tau}}_{\mathrm{tot}})$ obtained this system is $(10\ifmmode\pm\else\textpm\fi{}5)\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}21}$ s 49 MeV increases $(23\ifmmode\pm\else\textpm\fi{}5)\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}21}$ 61.8 indicating that dissipation energy. A comparison ${\ensuremath{\tau}}_{\mathrm{tot}}$ $^{18}\mathrm{O}+^{192}\mathrm{Os}$ populating same indicates influence entrance channel asymmetry on time. Dynamical calculations have been performed understand fusion dynamics these reactions it observed formation as we go from asymmetric symmetric channels. Also, predict 93% angular momentum lead a fully equilibrated whereas percentage decreases 84%, higher noncompound nuclear processes in latter case.
