Light charged-particle multiplicities in the evaporation residue (ER) and ssion (FF) channels from the reaction 200 MeV 32S+100Mo as well as ER and FF channel cross sections have been measured and compared to the predictions of the statistical model(SM) to estimate the ssion time scale. The statistical  model fails in reproducing the whole set of data and no convincing estimate is possible. In particular, while pre-scission   multiplicities can be reproduced, the model strongly overestimates proton  and alpha particle multiplicities in the ER channel, irrespective of the SM input parameters and  prescriptions used for the level density and the transmission coecients. Same calculations performed on data from literature in the A≈150 and excitation energy Ex≈100–200 MeV region, for the  ER channel, provide similar conclusions. These ndings repropose the problem of the reliability of the SM in describing the compound-nucleus decay and have a relevant impact on the extraction of the ssion delay time through the use of the SM
