The authors have measured two-fragment reduced-velocity correlation functions of the intermediate mass fragments (IMF: 3 {le} Z {le} 7) produced in multifragment final states for the Kr + Nb system (E/A = 35, 45, 55, 65 and 75 MeV). From the measured correlation functions they extract mean IMF emission lifetimes ({tau}) which are observed to decrease from ({tau}) {approx} 400 fm/c at E/A = 35 MeV to {tau} {approx} 125 fm/c at E/a = 55 MeV. For beam energies in excess of E/A = 55 MeV, no further decrease in {tau} is observed, indicating a possible saturation of the mean emission lifetime for IMF produced in multifragment exit channels.
