Pre- and post-scission multiplicities of proton and α particle have been measured in the reactions of ^1^9F + ^1^8^1Ta, ^1^9^7Au, ^2^0^8Pb and ^2^8Si + ^1^9^7Au, ^2^0^8Pb and ^1^6O + ^1^9^7Au. Pre-scission data show no systematic deviation from statistical model calculations if measured emission barriers for charged particles are taken into account in the transmission coefficient calculations. This suggests that the transient time during which fission widths reach a stationary value at saddle point is less than about 10^-^2^0 sec. Post-scission multiplicities of proton and α particle show steep increases with compound nucleus excitation energies.
