Abstract：
The cascade-exciton model has been used to observe the dependence of pion induced fission cross sections on the mass of the target. The analysis has been performed at energies 80 MeV, 100 MeV and 150 MeV for both the positive and negative pions. It has been shown that a single value of the ratio a_f/a_n can satisfactorily reproduce the experimental findings when compared with the available experimental data in the literature. The general trend of the fission cross sections with mass (fissility parameter) is seen to be low and slowly changing for the lighter nuclei, and it will steeply rise for the heavy nuclei.
