The energies of fission fragments transmitted through Al, Ni, Ag, Au, and U-Pd have been measured with surface-barrier detectors. The results, converted to the Lindhard-Scharff-Schiott (LSS) dimensionless parameters kρ (range) and ε (energy), were found to fit the empirical equation kρ=1.158ε1/2[1-exp(0.0987ε)]+0.01939ε in the region 12≤ε≤348. These results are 10-20% lower than those predicted by the LSS theory. A description is given of the effect of relatively simple modifications to this theory, and suggestions are presented for a more rigorous theoretical approach.
