Effect of particle evaporation in the 136Xe + 56Fe reaction and a reinvestigation of the 86Kr + 92Mo system

The nuclide distributions of Fe-like reaction products from 5.9 MeV/n 136Xe on 56Fe were measured as a function of excitation energy at a laboratory angle of 55.50 using the time-of-flight technique. From the measured distribution of yields the first and second moments were obtained in addition to the correlation coefficients and the isobaric variances. These results were compared with evaporation calculation. The comparison between our data and the results of the evaporation calculation shows that our data can be better described by the nucleon exchange model with the inclusion of the effect of particle evaporation. The isobaric variances were measured for the 430 MeV 86Kr + 92Mo system at 390 in the laboratory using the time-of-flight technique. Our measured variances are smaller than those obtained by Berlanger et al. at low energy losses and are in agreement with the results from the nucleon exchange model
