This thesis describes the measurement of several parameters of the neutral kaon system by the E773 experiment at the Fermi National Accelerator Laboratory (Fermilab ). A measurement of $$\phi_{+-}$$,the phase of the GP-violating amplitude ratio $$\eta_{+-}$$ has been made. The result, $$\phi_{+-}$$ = 43.53° ± 0.97°, helps limit CPT-violating effects in the kaon system. Precise determinations of the $$K_s$$ lifetime, $$\tau_s$$, and the $$K_L$$ - $$K_s$$ mass difference, $$\Delta{m}$$, have also been made, yielding $$\tau_s$$ = (0.8941±0.0017) x $$10^{-10}s$$ and $$\Delta{m}$$ = (0.5297±0.0037) x $$10^{10}$$ $$hs^{-1}$$
