The energy loss behaviour of fission fragments (FF) from $^{252}$Cf(sf) inthin Mylar ($H_8 C_{10} O_4$) and Aluminium absorber foils have been revisited.The aim is to investigate the observed change in the well known asymmetricenergy of spontaneous fission of $^{252}$Cf as the fragments pass throughincreasingly thick absorber foils. Two different types of absorbers have beenused: one elemental and the other an organic compound. The stopping powers havebeen determined as a function of energy for three fragment mass groups withaverage masses with $<A>$ = 106.5, 141.8, 125.8 corresponding to light, heavyand symmetric fragment of $^{252}$Cf. Using the effective charge (Z$_{eff}$) inthe stopping power relation in the classical Bohr theory best describes thestopping power data. Spectrum shape parameters, subsequently have beenextracted from the energy spectra of fission fragments for different foilthickness. The effective charge (Z$_{eff}$) correction term determined from thestopping power data is then used in the simulation for the absorber thicknessdependence of the shape parameters of the energy spectrum. The presentsimulation results are compared with the TRIM prediction. The trends of theabsorber thickness dependence of the spectrum shape parameters, for both Mylarand Aluminium are well reproduced with the present simulation.
